DNS and WINS problems (I think!)

[xirconuk]

Hi Guys

New to 2003 server (I come from a Unix background) and am having some problems.

Setup:

Mixed network of 95/98/2000/xp pro/2003 and a Sco 5 box all running on a Mitel 3100 voip phone system as network backbone.

4 XP pro m/c's form part of the 2003 domain, put in to run Pegasus Opera accounts and it is these machines that are causing the problem. These machines keep slowing down (including mine, which narrowly avoided going through the window today).

It is only the machines on the domain that are having problems, at one point if I pinged "office" it was going off site and pinging office.com! Got that fixed, but the slow downs are really getting to me.

The Mitel must run the DHCP server. Any suggestions on how to approach this problem? I have installed WINS on the 2003 server and tinkered with the DNS settings to no avail. At the point where I am going to reformat the server and stick XP on it and revert back to a simple peer to peer network.

TIA

Steve

Have you checked to see if the workstations are sending requests to the active directory server for DNS querys? If they are not querying the DNS server on the active directory server you will have all kinds of problems including slowness. The other thing to check is make shure the DNS server is set to forward DNS querys to any upstream DNS servers that you have so that it is able to resolve outside addresses. Without this you will be forced to sit through the timeout peried for every resolution it trys to make. Try checking ipconfig /all on the workstations and make shure everything is right it should have DHCP server as the mitel and DNS and WINS being the directory server if there not that is your bigest problem to fix first.

As far as I can see I appear to have setup everything correctly - what do you think?

I dont know what your issue is, but I can provide a useful tool that I use when I troubleshoot network issues as a part of my work.
