cannot start network connection service

[Thiru]

Hi,

I having a problem with my network connections.
I could not see the LAN and dial-up connection.
I think this problem happen after installing the SP2
beta version.
When i type ipconfig from c prompt is give a meesage
saying "NnetCfg.dll not found" but if i type ipconfig
from I386 directory then it works.
Another problem is i could not start network connections
service, it says the specific module not found.

I lookup up the problem in micrsoft site which says that
need the register the netman service using regsvr32
netman.dll but again when i do that,I get the
message "loadlibrary failed - the specified module could
not be find"

Can some one please help me to rectify this problem?

regards,
Thiru
