SBS 2003 Loses Connectivity after Userenv (1053) Errors.

A bit of background: My company's network is running SBS 2003 as a web application server (a setup that I inherited...)  using IIS 6.0, ASP.net frontend with a SQL 2000 backend. We process all our transactions with this system.

After three to five hours of uptime error 1053 from userenv (Windows cannot determine user or computer name, the rpc server is unavailable. GP processing aborted) will come up and nobody will be able to connect to the website hosted on the machine, and when attempting to browse to any website, IE will just show "http:///

The strange thing is, it can still browse to other machines on the network, and ping by hostname. It's pointed to itself as the DNS server. See below for the ipconfig/all from this server:

I've disabled offloading on the NIC and rolled back any recent updates. Also I've searched for hours, but cannot find anyone with the same symptoms....any suggestions?

Hello svaillancourt,

remove this dns server: 192.168.1.1
the ONLY dns server on an SBS (and also the clients) should be the SBS server itself.
rerun the CEICW and put any other external ISP dns server(s) in thAt wizard only.

Regards,

svaillancourt,

and btw, is this SBS server the ONLY dhcp server?

The setup is a bit strange, DHCP is not enabled. Its running on its own little (one machine) domain with a static IP address.
Also, I've done what you suggested in the first post, (made the only DNS server the address of the local machine.) Now time will tell.
it's normal that dhcp is not enabled, the SBS needs a fixed ip, but the SBS server should be the DHCP server, the clients should be on dhcp, provided by the SBS server, is that the case?
There are no clients. Its running as a stand-alone web server with no end user client machines.
hm, I wonder why you are using an SBS server since you are only using about 5% of the whole server.
AD is installed though, is it? what about exchange?
I'm wondering the same thing! heh .... its an inherited system from a predecessor. AD is installed. No exchange. And a big part of my troubleshooting this issue would be looking at the zones in DNS, however DNS is not listed under administrative tools.

Agreed. I installed/configured the other roles and it appears to be behaving now. But I really won't know for another three hours.
I guess you will bounce onto some more problems, because you also notice that that guy didn't know how to setup an sbs properly.
And, since this is sbs, everything is linked to oneother, but we'll see, we'll fix it :)
It is working now. :) I had to (re) install DNS, but after that. Not a hitch.

Thanks.
