FTP error event taking down server

I have an FTP server that has been on and off having the following error in event viewer:

“Unable to collect the FTP performance statistics. The error code returned by the service is data DWORD 0.” Event ID ~ 1000, source: FTPCTRS

Whenever this error occurs the server loses all network connectivity thus knocking my server off the internet and ‘causing downtime that is killing one of my projects. The info on www.eventid.net and technet does not give me any useful info. I am not to my best knowledge using the performance counters mentioned, can anyone advise how to find them and turn them off?

More importantly can anyone who has successfully run FTP server on a win 2k box, iis 5, sp2. Advise how I can resolve this problem?
