估计是有bug把:
http://support.microsoft.com/viewkb/viewkb.aspx?contentid=2459027
"Index was outside the bounds of the array" SMO error message when you connect to a SQL Server code-named 'Denali' CTP1 Database Engine instance in SSMS 2008 R2 and in SSMS 2008“
也就是在连接sql server2008r2和2008时,索引超出了数组的界限。就是你这个错误。
再打一下这个补丁吧:SQL Server 2008 R2 的累积更新包 5
