Network slow after removing old server - Why?

[Guest TSprau@gmail.com]

We recently replaced several old servers with one new machine that

does it all in one box. Removal of 3 of the servers went just fine,

but one of the old servers is causing problems.

 

The trouble-making server was running Server 2000 and was used as a

file server. All files have been properly moved, all shortcuts have

been changed, but when we disconnect the old server, the network slows

down noticeably. When we reconnect the server, the speed returns to

normal. I have watched the 'sessions' window for an extended period of

time, and I notice that various machines come and go quickly and few

are logged on for more than a few moments. It's as if the machines

want to 'check-in' with that server, but don't actually need anything

from it. The connections seem entirely random- it doesn't seem to be

linked to a specific OS or to a group of workstations or anything like

that.

 

Our IT director thinks it may be related to the fact that this server

used to run WINS, even though it has been shut off. We even turned on

WINS on a different server, just in case.

 

Any ideas? We want to send this machine to the boneyard.

 

-We use Desktop Authority, AD over DNS/DHCP, and use Win2000 DC's.

Is DNS on this server?

No. This machine was not a domain controller, dns server, or anything

more than a file and WINS server.

When you setup WINS on another server did you set this in the DHCP settings

then force all the workstations to renew their lease?

A few more thoughts: do you perhaps have the old server in the %path% or

some other environment variable on the workstations, were some printers

set up on it, or was it used as the installation source for some

programs? Was it a DC and some workstations still think that it is their

logon server (maybe need a reboot)?

 

Have a search through the registry on one of the workstations for the

server name - if you find it there, you may find out why they are going

to it.

We didn't force a DHCP renew, but we did shorten the lease length to

24 hrs. All settings on the DNS, DHCP, and DC have been switched to

the new server and new WINS server.

 

I did do a registry search and the old server did appear under the

'path' setting, as well as the new server. I will try to remove the

reference on more machines.
