We have a new client-server program installed on Microsoft SQL Server 2008 on a Microsoft Server 2008 box. When I log into the Client program on the SQL Server box directly, using my Windows NT authentication, I am able to access the program with no issues. However, I have installed the Client on a Citrix box to allow user testing. The client can access using the SQL SA Account with no issues. However, I get no response (no error even) when I attempt to login using my Windows NT authentication. I have setup the connection using cliconfg and an alias. I am using TCP/IP and I have ensured it is enabled. The reseller is suggesting that I upgrade my cliconfg. Isn't Client Network Utility installed as part of MDAC? I have 2.8 R2 installed. Any suggestions appreciated.
