Reverse lookup zones contain PTR records. Ben Winzenz, MCSE Network/Systems Administrator Peregrine Systems

Andy -----Original Message----- From: Rick Kingslan [mailto:[EMAIL PROTECTED]] Sent: 17 January 2002 13:40 To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] RPC Server weird error Andy, Good job on the AD zones. Congrats. As to the nslookup error, create a reverse lookup zone for your subnets, at least the one where the servers reside. Run though the reverse lookup zone wizard to create this by opening up the reverse zone, right click, new zone. Nslookup does and ip to name resolution, and what you're seeing is it compalining that it can't resolve the ip to the name. Still works fine - it's just cranky.

Although they were being updated by the DNS server, it wasn't working quite right. Following your advice, I deleted those 4 zones, and stop/started the Netlogon service. Ta da! The 4 zones showed up again, but this time nested below the domain name. No Userenv errors yet! One final thing, if you know - when I do an nslookup from any of the workstations, it says the following: e.g. nslookup www.google.com <http://www.google.com> DNS request timed out. timeout was 2 seconds. ***Can't find server name for address 192.168.1.200: Timed out *** Default servers are not available Server: UnKnown Address: 192.168.1.200 DNS request timed out. timeout was 2 seconds. Non-authoritative answer: Name: www.google.com <http://www.google.com> Address: 216.239.39.101 So, it does resolve the name properly - but what is all that stuff about not finding server name for address? Have I not configured a name for the DNS? If so, how do I do that? Thanks for all your help so far!

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....

Any suggestions on how I might check if they are using the full functionality of the DNS server, or something like that?

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!
