Slow Machines

[TidyTrax]

Dear all,

I have some PC's on one of my remotes sites running v v v slow. At this site we have numerous XP machines and one windows 2003 File server that was recently installed replacing an old windows 2000 F&P server. The DC's for network are at the main office and the link speed is 2Mbps

The problem is the PC's are v v v slow, applications "pause" and then run. But only when they are joined to the domain. If i remove a PC from the domain there is no problem. I have ran performance monitors, network monitors and there is no heavy use of the network, the processer, memory or the hard disks. I am looking for some pointers.

log into a client machine and type "set" from a command prompt - see where you are authenticating for these clients.

If you are authenticating over the wire, group policies, logon scripts, appliaction authentication back to the DC in HQ, etc. may all be a factor.

It does authenticate across the wire, but its always done that even before we upgraded the line to 2mbps, wasnt a problem until recently.

It is very bizarre

I am noticing a lot of activity on these machines from sms deployments, so im circling round that at the moment

Good stuff

Try shutting down the client piece on a machine or two (for SMS) and see if your performance comes back.

Where is DNS (and WINS, if configured) coming from? If DNS is coming from your central site, may be worth setting up a local DNS server to these slow machines.

TidyTrax - any applications being deployed over the wire?

Use Wireshark (a network protocol analyzer) to determine exactly what operations against DC cause slowdown...
