Windows server administration - URGENT

We have a problem with a Win2000 server running ColdFusion MX and SQL2000: IIS, FTP,SMTP,WWW services will just stop all of a sudden service recovery properties of these services all reset to take no action on fail (previously they are set to restart on fail) we can restart the above services OK , but they keep on stopping 2 - 3 times a day with no specific error in the event logs We need somebody to check over the server, find the problem and rectify it ASAP. When posting bids, please give details of your experience and skill levels. We are looking for a long-term relationship with a Windows sysadmin, so your information will be essential to us.
