RE: [ActiveDir] RPC Server weird error

Andy,   I'd run DCDiag - all options.  This ought to turn something up.  You might also consider nltest (NLTEST).   This is most likely a DNS issue.  Make sure that the 4 zones are configured and available below your domain name in DNS.  You should find _sites, _msdcs, _tcp, and _udp.  This is where the SRV (Service Locator Records) are going to live.  If they are not all there, make sure that you have Dynamic Updates set to 'yes' or 'Secure Updates', then stop and start the netlogon service.   And, to answer your question, RPC server is the process that is responsible for all the essential communications on a Windows NT platform - workstation or server - internal or external.  It's the Remote Procedure Call services.   Feel free to send your DCDIAG or NLTEST logs to me and I'll help you decipher what's what.   Hope this helps....   Rick Kingslan - Microsoft Certified Trainer   MCSE+I on Windows NT 4.0   MCSE on Windows 2000   MVP [Windows NT/2000 Server] mailto:[EMAIL PROTECTED] "Any sufficiently advanced technology is indistinguishable from magic."   ---  Arthur C.

Approximately every half-hour to hour, each workstation will log the following error in the Application event log:   e.g.   Source: Userenv Category: None Type: Error Event ID: 1000 User: NT AUTHORITY\SYSTEM Computer: FLUMP   Description: Windows cannot determine the user or computer name. Return value (1722).   I did the obvious NET HELPMSG 1722 and it tells me that 'The RPC Server is unavailable'. I have also looked all over the web for ways to fix this problem, and can't find any. They all seem to give me really unuseful information, like 'Make sure your DNS is configured properly' and other such useful tidbits. I am really lost here! None of the workstations experience any problems, whatsoever. They all work fine, log on fine, use Exchange fine, register in the DNS fine etc etc, can browse the network and web. They all work fine. BUT I can't get rid of this error message, which just keeps on showing up. The client is convinced something bad will happen, and I just need, for my own peace of mind, to solve this one - and the web has turned out to be useless for tracking down a resolution.   BTW, the server is Small Business Server 2000 (SP2) and is experiencing no problems.   Thanks all in advance, I would be really grateful if someone could shed some light on this one!   Andy Ward MCP (Exchange 2000) GCS   PS What the hell IS an RPC server anyway?
