RQC problem

I posted this question in the Win2000 Network section and it has gone
unanswered for over a week now. Is there anyone here that can help with this?

Hello everyone,

Here is the situation that I'm having trouble with; Windows 2k3 Ent. VPN
server setup with quarantine control, RQS.exe is running correctly and
Windows XP Pro/Home computers have no trouble connection while using the
RQC.exe. The Windows 2000 machines are unable to pass the RQC.exe program.
All the systems meet the security requirements; it just doesn't seem to run
the RQC.exe application properly.

The Windows 2000 computer rqc.exe reports a "-1" error. I enabled the
rqc.log file using and get the following entry in the log file when the
Windows 2000 attempts to get removed from quarantine:

[484] 13:29:18: Info: Usage: rqc.exe /conn ServiceProfileName [/domain
DomainName] [/user UserName] [/port PortNumber] [/sig Signature] [/log
LogFileName] [/?]
[484] 13:29:18: Info: /conn Required. Specifies the name of the service
profile for which you want to run RQC.
