Recently browsing the network neighbourhood has become very slow.

We have mostly Win2K Pro sp4 clients with NT4 sp6 as DCs.

Network Neighbourhood is very slow, probably about 45 second to show the computers in the domain.

also, enumerating files in a 'save as' folder drop down dialog also takes much longer then it used to.

The only thing which has changed (that I can think of) is, we installed a 'TEST' domain for some tests we were doing.
This domain is gone now though.

Our WINS runs on 2 win2k servers.

Any ideas ?

Thanks

In your case I guess some scheduled tasks that are not handled as they should by the OS. That's a common issue that can be solved.

Speed Up Network Browsing

If you are using your Windows XP machine on a network and trying to access a Windows 98 or Windows Me machine and network response is slow?

 

Well here is how to fix it In XP, select Run from your start menu. Type "Regedit" in the box and click OK. Once you're in Regedit, navigate to

 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\RemoteComputer\NameSpace

Now, simply delete the two keys (a lot of long numbers and letters) under this, which are the "Printers" and "Scheduled Tasks" keys. You can still share and use printers, so don't worry.

 

This tip works on ALL Windows 95/98/ME and NT4/2000/XP PRO systems with MS Internet Explorer 4/5/6 or later (after Service pack installation) installed.

This Registry fix speeds up internet/remote (using Windows Explorer and/or Internet Explorer) browsing process considerably on most MS Windows 32-bit machines connected to a network and/or remote computer(s).
This actually fixes a BUG in MS Windows OS's that scan shared (remote) folders/files across the network for Scheduled Tasks, and can add a delay as long as 30 seconds, because it uses extra time to search the remote computer(s).

Tried that reg fix. Seems to work. Thanks!

thanks but...when I click 'Entire Network' / 'Microsoft Windows Network' it takes ages to enumerate the domain.
There is only one domain, so why the delay ?

When I click the domain, another looong wait before the machines come up.

Lan Manager.
 Your WINS are on W2K servers... Why not upgrade one or both of the NT4 boxes?
NT4 is ok, but the benefits from the AD domain is great.
Part of your issue stems from Lanmanager, which is the Auth method used by NT4. This probably isn't the entirety of your problem, but that would seem to me to be the first place to look. I assume your network is DHCP, and you have correctly configured your scope option to point WINS at your 2K box; But with all that in place, your PC still has to meekly inquire after the Browse Master, which in your scenario is on the PDC. LanManger is slower than AD authentication, which relies on DNS instead of WINS.
MJoyceAuthor Commented:

yeah, I have plans to move to AD in december.
I just don;t understand what caused performance to change, it never used to be so slow.

The nt4 boxes are old though.  cant wait to switch them off.

I actually had to install NT4 today, eugh, I had forgotten how horrid it is.

...roll on december.
MJoyceAuthor Commented:
I think this was to do with having an old install of VMware installed.  

Trying to enumerate a uncontactable domain or some such.
Casca1Commented:
Interesting.
Have you removed, or at least reconfigured VMWare?
MJoyceAuthor Commented:

I disabled the vmware virtual nics and browsing speed returned to normal.
Casca1Commented:
Ahh; Cool...
