I've ZCM 10.0.1 on W2K3R2 SP2 server, My wks are XP SP2.

A lot of wks show warning on log events, I don't find anything about these...

WifSender.Initialize failed.{}

When I check time of this error, It's seems to happend on login or loggout...
I don't detect something wrong on these wks.

Anyone know what this message mean?
