Default Login failed for user 'null'
Hello,
I have problem with linked servers (MS SQL Server 2k)- when I try to execute
query(update, insert..) with linked servers, I have message Login failed for
user 'null'. This is very strange problem, some computers in AD (2k3 std)
don't have this error, when the other have this problem for few hours and
some have this error all the time. Network Protocols is TCP/IP.

Any idea ?

Check out "Login Delegation" in the BOL.
