XP Clients being forced offline
We have XP clients with Home (H) Drives mapped via a DFS namespace to a 2003 Ent x64 server. Each user has their My Documents sync'd to their H drive. Several time throughout the day users are forced offline. This is affecting users connected to different LAN switches (3COM) but not all users on those switches. I've had a ping running to the file server which does not time out when the client is forced offline. Users can click the offline icon and sync to re-connect.

edster9999 - thanks for you comment, we have checked utilisation etc but the issue is not affecting all users connected to the switch.
are you using vlans on the switch ?

No not on any of the switches. I'm not sure if it is a network issues or an OS issue...?
SP1 has a bug in it that can cause some Domain services to stop intermittently. Domain services are defined in this case as things like (AD, DNS, DHCP, Terminal Service, Exchange, ect...)
The fix to this is to download and install SP2:
For details see this link, that recommends a hotfix, but SP2 covers this gliche:

I can provide you examples of almost any individual service being knocked down. Here is an example of DHCP:

Also, if you have Windows 2000 pro clients that are not showing problems. This is an example of portfast not being enabled on the switches for the computer ports. XP boxes will time out if portfast is dasabled. If you wish for information on portfast, please reply "tell me more".

CheifIT - The file server is SP2 R2. We do not have any 2000 clients so am unable to comment on that. I did look at some other posts and came across portfast. If I have spanning tree disabled does that imply that portfast is enabled? Other than having a 2000 client on the network, are there any other tests I can do?

That is correct.
That is correct.
So, are we talking all of your boxes being knocked down or just a select few?
ASKER
The issue is not affecting all boxes. A mixture of desktops and laptops as they all have offline files enabled. I've ensured spanning tree is disabled on all switches and have been monitoring the switches today. I can see no issues on any of the switches. I'm wondering is this is more of a software issue than a network issue?

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
If they are switches they should either have monitor software or a telnet area where you can check stats.
Or at a very basic level watch the leds on the front. Check CPU or utilisation
