very slow logon from XP pro workstation

we have a single microsoft small business 2003 server, and 5 xp pro workstations connected in a small network. We are also running exchange. This network has been running fine for the past year, but we are now experiencing speed issues when logging in from each workstation. I have checked the DNS and all looks fine. I can confirm that when we restart the server, it seems to resolve the problem for a short while, but we do not want to have to do this every day. The exchange mailboxes are pretty empty.
Does anyone have any suggestions as to how we can resolve this issue?

Hello nigelbeatson,

Slow logons is mostly due to DNS issues.
Can you copy past the ipconfig /all of the server and one worksation please?
Do you see anything strange in the eventlogs of the server/clients?
Did you add these clients the correct 'connectcomputer' way to the domain?

Regards,

suppsaws

I'll second that opinion - you say DNS if fin but in over 90% of cases incorrectly configured DNS is the problem, DNS *MUST* br configured as follows.

1. All workstations *MUST* point to the internal DNS server (normally the Domain Controller), ONLY. This is configured either in the TCP/IP properties on the Network Connections for static IPs where the internal server must be the preferred and only DNS server, or in the DHCP Options in DNS where the internal DNS server must be the only server listed.

2. Your Server *MUST* have a static IP and the preferred DNS server should point to itself

3. Ti resolve external names, set up forwarders to point to your ISPs DNS severs as detailes at http://www.petri.co.il/configure_dns_forwarding.htm, this is the ONLY place any external DNS servers should be registered.

Thankyou for your input. I am going out to this site later on today, so will update everyone at that time. One thing I would point out is that this server / network has been working fine for around a year, and none of the settings have been changed (by design anyway!) since then. Update later.

Sometimes the issue can emerge when an external DNS server is specified as an alternate DNS server, most of the time its neve used and everything works fine, but if the preferred server becomes busy, the clients will switch to the alternate server and from that point on all internal name resolution fails and logon slows down or does not happen at all.

the forwarders need to be configured in the 'connect to the internet wizard'.
Rerun that wizard and place your ISP dns servers there.
Also, is your server the DHCP server for the domain, or is DHCP provided by a router? (which is not good)

I have checked out this site and manually removed the workstation from the domain, deleted the computer from the active directory, renamed the workstation and tried connect mycomputer again. It goes through fine, right up to the point where it usually restarts, and after a short delay, we get the error "An error occured when configuring networking settings. See your network administrator."
Therfore the workstation cannot be added. I can add the workstation to the domain manually, but the login hangs on applying computer settings.
I can login locally.
I tried the other problem workstation and the connectcomputer util seems to have resolved this. Any ideas?

OK. I hvae now resolved this issue. Not sure what the underlying problem was, but when I returned I managed to re connect the problem workstation with the connectcomputer wizard, where previous attemts had failed. It's now working fine. Thanks to all who helped.
