Guest Jeff Posted November 15, 2007 Posted November 15, 2007 I have approximately 100 users on our network that consists of 7 servers. There are approximately 1 dozen users that get disconnected from one server consistantly. That is a W2K server with network shares. I am pretty sure it is a DNS issue because I can ipconfig /release /renew and that works (most of the time). Sometimes I do not even have to do that, just click on the shared drive and it comes back. Thanks, Jeff

Guest maxime Posted November 16, 2007 Posted November 16, 2007 Re: Disconnected network shares Have you recently added any hardware (router /Access Point / network printer / network card something like that can derange the network? I tell you this because this week i had the same symptoms And it was a malfunctioning access point from SiteCom. I don't know if this info is relevant. but it's free so their you go :) "Lanwench [MVP - Exchange]" wrote: > Jeff <Jeff@discussions.microsoft.com> wrote: > > I have approximately 100 users on our network that consists of 7 > > servers.

Guest Jeff Posted November 16, 2007 Posted November 16, 2007 Re: Disconnected network shares when I run nslookup, I get a list of 8 ip addresses. I only have 3 Domain Controllers. Those three are listed, but then I have 5 others listed. I can identify four of the others as local computers, but the final one is a dead IP that I had used in the past. What could cause this and how do I fix it? Jeff "Robert L.

Guest Jeff Posted November 16, 2007 Posted November 16, 2007 Re: Disconnected network shares On another computer, I run nslookup and there is a message of non existant domain, but then it lists 4 servers. three of these are different from the other computer. Two of these are Exchange servers (one of which is a DC), one is a file server on our network and the other is a local pc. Where does this information come from? Obviously I have a problem somewhere.
