We have two load balanced WFE with several web applications on port 80. For each site there is a correct AAM and host header. We use sticky sessions on the load balancer.
The problem is now that when a user makes a POST to a web service (in this case for Excel Services and Reporting services) the request is sent to the load balancer again and then to the other server. As we use NTLM this double hop will make the request fail
with a 401.
I have read the documentation for Reporting Services (8.2 in here:
http://msdn.microsoft.com/en-us/library/ee384252(SQL.100).aspx">http://msdn.microsoft.com/en-us/library/ee384252(SQL.100).aspx) and it pointed to a solution where you put the host header in the local host file for each WFE. This would make the request
stay on the same server. It worked perfect in our test environment but in production it doesn't work. If I PING the adress then it points to the local server so it only seems that SharePoint ignores the HOST file.
Has someone experienced this type of problem?
