Admin share after sp2

Greetings,

Just installed SP2 on my machine and disabled the
firewall. When I use the admin share
(\\server\C$\WINNT\System32\Usrmgr.exe) linked to an NT
domain server I get an error saying the specified
procedure cannot be found. The same with server manager
which just crashes without and error. All are on the same
domain. These shares, of course were working with SP1.
Anyone have this problem or know a solution?

Thank you in advance,
carsen
