Intermittant error: "A connection attempt failed because the connected party did not properly respon

  

Greetings,

I'm having a doozy of a problem, and can't find a solution.  I have a WFC Web Service installed to a pair of servers, and accessed through a load balancer.  I am accessing the service from an ASP.NET client app, also via WCF.  The Client is not load balanced.

I'm getting an intermittant error:

(Inner Most Exception) System.Net.Sockets.SocketException:  A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond x.x.x.x:80

Hi folks,

I am using VS 2010 Professional with SQL Server 2008 Developer.  I right click on the App_Data folder in solution explorer and add an existing item, then navigate to the correct database.  However, I receive a pop up that Access is Denied.  How do I fix this? 


cannot attach database from server explorer

  

Hello all,

In Server Management Studio, I am attempting to attach a database.  After selecting the database in the wizard

I receive an error: This file is in use, Enter a new name or close the file that's open in another program. 

I don't have SSMS open, and have restarted the computer to make sure the memory is cleared.  Not sure what to try next.  Any ideas?


need help about HttpWebRequest : A connection attempt failed because the connected party did not pro

  

Hiiii

I am creating an application for bulk mailing. Its on my subdomain. 

The functionality i require here is I need to copy an html file located in different subdomains on my production server to my bulk mailing application. 

I am using HttpWebRequest for the purpose where I take the url of the page into a text box and create a HttpWebrRequest. 

The code is as simple as follows.

HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://mydomainorsubdomain.com/dir1/page.html");

and this is working fine on my local development environment that is in VS2010 

but when i put code to production server it is throwing following error.

Detach/Attach database question

  
I recently restored a database from SQL7 to SQL2005.  When restoring the database I needed to create a c:\data\data folder or else it would not restore the mdf and ldf files. I would like to move these files to a new location.  Copied the the two files to a new folder, C:\database.  Using the sql studio manager, preformed a task to detach the database, then attach the database with the new location. This seemed to work, I am able to access my application that uses this database.  However, any changes I make to the program, are not writing changes back to the mdf file.  When I open the program, these changes are still in place, but the mdf file should be updated, correct?  When the database files were stored in the c:\data\data folder, any little change I made to the program changed the modified time for the mdf file. Is there something missing or where could these changes be written to?

I have SQL'08r2x64 freshly installed on a WS'03r2x64sp2 box and WS is also a DC (sorry).  Previously, there was a SQL'05sp3 installation on this box and it worked splendito.  I used the SQL'05 for some minor devel and to host a Backup Exec 11D db/installation; it all was splendito.   Then, i removed SQL'05&BE11D to prepare for an upgrade of this arrangement.  Next, i installed said SQL'08 to be the foundation for a planned Backup Exec 12.5 install.  To date, I can't get to a clean install of SQL'08 and thus have not progressed to installing BE12.5.  I now have this painfully annoying situation (as i've been beating on it for 2 days) where a series of errors occur during boot: 1st: srmSvc; Event ID 12317; File Server Resource Manager failed to enumerate share paths or DFS paths.  Mappings from local file paths to share and DFS paths may be incomplete or temporarily unavailable.  FSRM will retry the operation at a later time. 2nd & 3rd (occurs twice): MsSQL$buExpressSQL; Event ID 18456; Login failed for user 'BOWMAN\ExecSQL'.

Cannot crawl sharepoint site and mysite after database attach upgrade form sharepoint 2007 to 2010.

  
After database attach upgrade site and mysite from sharepoint 2007 to 2010 , I have full crawl and get "The crawler could not communicate with the server. Check that the server is available and that the firewall access is configured correctly. If the repository was temporarily unavailable, an incremental crawl will fix this error. ( Error from SharePoint site: HttpStatusCode ServiceUnavailable The request failed with HTTP status 503: Service Unavailable. )" for mysite and get "Access is denied. Verify that either the Default Content Access Account has access to this repository, or add a crawl rule to crawl this repository. If the repository being crawled is a SharePoint repository, verify that the account you are using has "Full Read" permissions on the SharePoint Web Application being crawled." for sharepoint site. The content access account for search is "db_owner" of both of site and mysite. How do I solved this problem ?
