The issue is basically we have 2 patch versions of 8.82 running. The one on our old server box which is production is running 8.82 pl15 (SQL server 2005) and our new box 8.82 pl19 (SQL server 2012). The funny thing is the client works perfectly fine when finding the current production machine when using brand new windows logins, but the one that used the whole time on this machine has issues finding the SQL 2005 server, I think it is something either the registry or users folder as I uninstalled the SQL 2012 navigate client and only have the one for SQL server 2005.
Right the machine is running on B1 Pl15
