URGENT HELP! - XP Browsing NT4 Network & Drives SLOW
Posted on 2003-11-06
I need this one sorted over the next few days so I'll put good points on it..
I have a network over 2 sites with NT4 sp6a PDC & BDC.. the remote site with the BDC (TS) is having the problems. Everything has been running fine for ages now there is this.. The windows XP machines take a long time to list network drives and files.. So bad in fact that their office applications have gone to not responding (runnign XP Pro SP1 and Office XP SP2).
I have spoken with the users and got them to open up my computer and go \\server .. users have reported up to 20 seconds with little network activity besides a few flashes before the list of shares comes out.
I have a windows 2000 server also that I have been using remotely to do the same thing .. \\server and it comes up instantly..
It will also take a long time to open up files from the network, and open up their network home drives.. They also have their PST files on the server and it takes a long time to switch between emails ..
All of these problems come and go in severity. I have run disk and network NBT connection monitoring on the server and all seems fine .. in comparison to my server here also NT4 it has less usage. I have noticed some activity of the Avg.Disk Queue Lenght counter. on default scale (100.00) this can go from nothing for ages ... and spike to 12 over a period with an average of maybe 4-6 ... should I be concerned about this?? or is it normal ? Some times it may spike to 40 for a couple of seconds ?? Would this affect other users ?? as from what I ahve seen from monitoring an XP user will be on the phone telling me its slow to browse while there is basically nothing happening on the server...
My questions are:
1. why would this happen all of a sudden?
2. what should I be trying to rectify / test this.. I have done research and read about reg fixes and hosts files specifying the server name and ip in lmhosts or hosts... but I wanted to see what you all think??
I will be up on site on Tuesday next week and would like to try a few things before going up... any help would be appreciated.
Thanks in advance..
