Client can't connect to WCF on deployment machine Windows 2003 Sp2 server .NET 3.5

Posted By:      Posted Date: April 14, 2011    Points: 0   Category :SharePoint


I have a WCF service hosted in a Windows service application.  I have a Windows Form client that connects to it.  I am using net.tcp binding for two endpoints.   It all works fine in my environment, but when I deploy it on my cutomer's machine the client does not get a response from the service.

I ran netstat -na and I can see the endpoints listening.  I can even see the connection ESTABLISHED when my client runs the first method.  But my client times out and receives a "Could not communicate with XXX service.  This request operation sent to net.tcp..... did not receive a reply within the configured timeout (00.01.00) The time alloted... etc"

I tried removing all security from the configuration file, but that did not make a difference.

I reinstalled .NET Framework 3.5

I added     System.Net.ServicePointManager.DefaultConnectionLimit = 200 as suggested in another post.

I am creating a trace for the client and the server.  The server does not log any activity of a connection.  The client is catching a communication exception.

Any insight would be greatly appreciated.  What else can I try to see why the client is not able to chake hands with the server on this particular machine?

Many thanks,

NLB over windows server 2003 Cluster on the same machine group

Hi Guys, I should install MS SQL 2005 cluster on windows server 2003. There will be 2 servers in the group. Meanwhile i should set up load balancing for web application again there will be 2 servers in the group. My question is the following, as the load of the servers aren't high is it acceptable to setup load balancing and clustering service onto same windows server 2003 machines group. i.e. the same 2 servers will be a member of Load Balancing and MS SQL Clustering groups?   pls advise. thx

Net.TCP Endpoint; Windows Authentication security; client can connect to a server at localhost but n


Hey all, so here's what going on:

I have a WCF Service that I have setup as a Windows Service.  Everything works perfectly when I attempt to use the system with all of the components (i.e. server and clients) on the same machine.  However, when I try to connect my client from a different system, I get an error that is trying to tell me that the server rejected the client's credentials.

I need the client to the able to connect from a different machine.  I want to implement a SQL Role Provider kind of credentialing in the future, but for now, I just need it to work.

What I have tried
I have looked around online and read a few other posts as well some things in the MSDN KB and I have either not found the answer, or not understood it.

  • I have tried setting the <security mode="Transport"> to "None" with the hope that that would disable the accreditation entirely.  All it did was result in a different error saying that there was an error that might have been caused by an invalid message.  I have also tried a few other configurations with this element in the app.config file; to no success.
  • I have read some things about Impersonation, but I am not quite sure I understand how to implement it

Deployment of SharePoint Server 2010 on Windows 2003 Server Std Ed


After reviewing http://technet.microsoft.com/en-us/library/cc262485.aspx document on hardware/system requirements it appears that I will need to upgrade my Windows 2003 Server Std Ed to at least Windows 2003 Enterprise Ed in order for SharePoint Server 2010 Ent to be able to address more than the 4 GB (I believe) Windows 2003 Std only allows or addresses.  I have 32GB RAM on my Windows 2003 Std which also hosts the SQL Server 2005 Std Ed databases for other apps and will host SharePoint's database, as well--single platform install.  I also have two CPUs on this box which SQL (32 bit) uses.

So my question is:  can I easily upgrade Windows 2003 Std Ed to Enterprise without having to reinstall Windows 2003 and subsequently all other apps in Windows?

Deploying an .asmx Web Service on a Windows Server 2003 machine

Hi, I have created a WEb Service using Visual Studio 2008 on an XP PC. I have sucessfully deployed the web service and tested it correctly on my local machince. It is located at http://localhost/MAC/Service.asmx.

Now, what I want to do is deploy this Web Service on a server. The server is running Windows Server 2003 Web Edition. I thought it was only a matter of copying the "UMACS" folder on my XP PC, which includes the Service.asmx, web.cong and service.cs files etc, and then copy this to the server and try to deploy it through IIS.

I have tried this but everytime I try to access http://localhost/MAC/Service.asmx like before, I get "Error 404: Web site cannot be found". I have done a lot of searching on this. I have enabled IIS apping use the command "c:WINDOWS\Microsoft.NET\Framework\1.1.4322\aspnet_regiis.exe -i" but still this doesn't work.

Is there something else I need to do to deploy this web service?

In the IIS on the server, there is a "Web Service Extensions" section. Do I have to do something in here first to make it work?

WCF Windows Auth (NTLM) Problem when Client and Server are on the same machine

Windows Server 2003: Discover Improved System Info, New Kernel, Debugging, Security, and UI APIs


There's a lot to say about Windows Server 2003. First of all, it's the first operating system with built-in .NET Framework support, and it's the first 64-bit OS from Microsoft. But wait, there's more! There are lots of new features and APIs in this version as well. For instance, Windows Server 2003 features Hot Add Memory and a number of other arcane new tidbits. There are new APIs for handling threads, directories, and files, and new features like the low fragmentation heap for managing memory and system information. There's vectored exception handling and new UI APIs as well.OS internals expert Matt Pietrek takes a look at the additions he finds most interesting and useful so you'll have a good place to start when you dive into Windows Server 2003.

Security Briefs: Exploring S4U Kerberos Extensions in Windows Server 2003


Building Web sites that provide services external to the corporate firewall is tricky. Usually it's not desirable to grant corporate domain accounts to external clients, and from a purely practical standpoint Kerberos does not work well over the Internet due to the typical configuration of client-side firewalls.

WCF Client (netTcpBinding) does not connect to remote DNS on Vista and Windows 7

Hi, WCF Client (netTcpBinding) does not connect to remote DNS on Vista and Windows 7. With other OS like XP and Windows 2003, client connects to remote DNS properly. I got the following exception. Same client works in Vista and Windows 7 if service is available in local network. Following are the exceptions: <Exception> <ExceptionType>System.ServiceModel.EndpointNotFoundException, System.ServiceModel, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089</ExceptionType> <Message>No DNS entries exist for host icelive.theice.com.</Message> <StackTrace> at System.ServiceModel.Channels.DnsCache.Resolve(String hostName) at System.ServiceModel.Channels.SocketConnectionInitiator.GetIPAddresses(Uri uri) at System.ServiceModel.Channels.SocketConnectionInitiator.Connect(Uri uri, TimeSpan timeout) at System.ServiceModel.Channels.BufferedConnectionInitiator.Connect(Uri uri, TimeSpan timeout) at System.ServiceModel.Channels.TracingConnectionInitiator.Connect(Uri uri, TimeSpan timeout) at System.ServiceModel.Channels.ConnectionPoolHelper.EstablishConnection(TimeSpan timeout) at System.ServiceModel.Channels.ClientFramingDuplexSessionChannel.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.Comm

Unable to connect to SQL Server 2005 remotly, all client protocols are blank

I have an installation of SQL 2005 and had issues connecting remotly. Looking at the client protocolols, they are all blank. I can see that TCPIP, Named Pipes, VIA, etc. are 'enabled', but where the words 'TCPIP', 'Names Pipes', etc. should be, it's just blank. I tried to install SQL 2008R hoping the Client Protocols would be corrected during the installaion, but they were not. I'm assuming the issue with the Client Protocols not showing up is a symptom of the problem. Does anyone have any ideas? Thanks!

SQL-Server 2005 x64 / windows server 2003 x64 crashes during file copy

Hi We are running: Microsoft SQL Server 2005 Standard - 9.00.4294.00 (X64) Microsoft Windows Server 2003 R2 Enterprise x64 We have gigabit interface. Today we copied a file (using robocopy) from our databaseserver to another server (backup-server). The copy was started from the backup-server and source were specified using UNC. The copy were using about 20% of the bandwith (about 200Mbit). During the copy, sql-server reported several errors, for example: AppDomain 15 (mp.dbo[runtime].14) is marked for unload due to memory pressure. The client was unable to reuse a session with SPID 75, which had been reset for connection pooling. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message. ***Stack Dump being sent to [PATH\SQLDump0005.txt Resource Monitor (0x1384) Worker 0x000000008000C1C0 appears to be non-yielding on Node 0. Memory freed: 0 KB. Approx CPU Used: kernel 15 ms, user 218 ms, Interval: 428541. So to me it appears that sql-server crashed during a file copy. We have 27 GB ram. With 24.5 GB dedicated to SQL-Server. The files we copied were quite large, some over 50GB. I found a similar issue about this: http://support.microsoft.com/kb/920739/ Do you think the issue above could be the cause of the sql-server crash? ///Patrik

Sharepoint 2003 + Windows Terminal Server 2008 + Office 2007 problem?

Hi, We have a customer where some users runs Windows Terminal Server 2008 with Office 2007. They open documents from a Sharepoint 2003 site. When they open an excel sheet they get a button in the document which says "Server workbook: Click edit workbook to edit this workbook" and there is a button: "edit workbook" The users clicks "edit workbook" but get an error message saying there is no connection to the server.  They are able to edit the document, but not save it back to the sharepoint site. Most other users work on their local computer with Office 2003. Here, everything works fine and there are no button/message stating its a server workbook.   Is this caused due to some compatability issues between Sharepoint 2003 and Office 2007?   Best regards, Thomas Hansen ErgoGroup AS
