Problem with computers dropping off network
Posted on 2009-04-30
So I have two windows 2003 servers
Server1 has always been in this office, Server2 is from interstate (was the PDC at the interstate office)
Also server2 was on a diff IP range before it came into office, i have since put it on same IP range as server1
Users are getting booted off the network at random points, everything drops out they lose their IP address/network/internet etc. Sometimes a reboot fixes it, an ipconfig /release and renew also can fix it
I need to know where to look and whats going on, have taken this network over from someone else and it hasnt been worked on for over a year i'd say
Need help please!
im also getting this error on SERVER2, not sure if its relevant
Product: Windows Operating System
Event ID: 5802
Symbolic Name: NELOG_NetlogonNoAddressToSiteMapping
Message: None of the IP addresses (%2) of this Domain Controller map to the configured site '%1'. While this may be a temporary situation due to IP address changes, it is generally recommended that the IP address of the Domain Controller (accessible to machines in its domain) maps to the Site which it services. If the above list of IP addresses is stable, consider moving this server to a site (or create one if it does not already exist) such that the above IP address maps to the selected site. This may require the creation of a new subnet object (whose range includes the above IP address) which maps to the selected site object.
