When I startup my Win7 pc,I logon to our corporate domain. Using the Sql Server management studio I'm able to connect using Windows Authentication to our local db server.After I establish a VPN connection from my pcto a domain of our client, I get te following error when I try to connect to our local db, using the Sql server management studio, still using Windows authentication:Login failed for user <OurLocalDomainName>\Guest'. (.Net SqlClient Data Provider)How did I become a guest on our own network?Or better, how doI prevent from becomming a Guest?

After a long search I found it. Seehttp://social.technet.microsoft.com/forums/en-US/itprovistanetworking/thread/275599f0-6239-46a5-8245-50a5c13a2713/
