Can't connect from a vista client to SQL 2005 box,other machines work fine

Hey. I've a windows vista machine which can't connect to SQL 2005 box. Other machines which are lower than vista work fine. Also, vista box can connect to other SQL 2005 instances but can't connect to only one instance. But, I can connect to the instance fine from my XP box. Also, it's not a permissions issue. This user is an SA and can connect form some other machine. SQL 2005 box is at 2047 version right now. And, the user is able to connect to some other boxes which are also at 2047. Please help. Thank you

Add the account sepcifically to the SQL Server. When you connect from Vista (because of the UAC) it strips out your group SID from local admins, so SQL Server doesn't know who you are, and that's probably what is causing your issue. Add the user's account by name to the box.
