I'm having some trouble with a DHCP glitch. If any of you with Windows exerience can help, I'd be very grateful!

This first reared its head last week (just once). Today I can't keep a DHCP lease for more than a few moments. IP based drive mappings die during login. Ipconfig reports no leases. The lease can be renewed, but then it mysteriously looses its gateway. The next lease renewal fails completely. These three commands were ran just moments apart.

My best guess for such a flaky problem is layer 1. What do you think?

Thanks! Rob

The DHCP server is administrated by central services. I can't administer this server and... believe it or not... they haven't responded to my incident report for two days. :-(

Just mine. It is slightly different... the only 2000 machine on the floor and has an internal DNS entry (IP is still dynamic).

I was hoping someone where would have some advice because (2 days!) our network support is terrible and sending them in the right direction certainly helps.

The last reply in this thread might be a possible answer:
http://www.tek-tips.com/gviewthread.cfm ... qid/739110

If not try a google search for: The following error occurred when renewing adapter Local Area Connection: DHCP Server unreachable (copy and paste that into google as is -- about 116 results)

The other results may provide additional ideas.

I think my other suggestion would be disable DNS. If everything else is automatic, the domain server should also provide the DNS entry automatically anyway (assuming the network admin has it set up correctly.)
