I have a user whose laptop is having the settings for "Append primary and connection specific DNS Suffixes"modified mysteriously.

This is under Network Connections, TCIPIP, properties, Advanced, DNS
(user is using Windows XP Prof /sp3)

The radio dial changes from "Append primary and connection specific DNS Suffixes" to
"Append these DNS suffixes".

Not sure who or what could be changing it.

Please let me know any ideas.

Is it happening on each restart or periodically?

As this in a domain environment?  If so, Group Policy or a login script could be changing this.
If it's local, look for a local policy by running gpedit.msc.  Look under Computer Configuration - Administrative Templates - Network - DNS Client.  Check each policy that has suffix in it.

You can always set the local compute policy to make the appropriate changes.  Local policy will overwrite any group policy, or network setting (as long as the log on script or whatever is changing it does not run after the local policy).  However, last time I looked local policy, runs last and overwrites all other settings.

Another reason why it is so important to set you permissions and policies to be as strict as possible.

t_hungate : "Local policy will overwrite any group policy"

This is wrong. If a group policy (AD)  is being applied to your computer then it will override the settings in the local policy.

This is only happening to one user.  He has the same computer image everyone else has in the company.  It's happening periodically.  This is a domain environment.

A malware / spyware might be doing this. Scan with a couple of antivirus software to be sure. You can use HouseCall services of Symantec, TrendMicro, McAfee...etc.

Also a utility (i.e. like wireless NIC's own utility) might be doing this.
As a first step, can you run the command below and restart the PC to see if it is happening again.

C:\> netsh int ip reset c:\resetlog.txt

This command will reset the IP configuration and c:\resetlog.txt will be the output of resetting process.
If the NIC is configured to use a static IP or DNS server, you must note it first and put it back after executing the command.

After trying this, you might consider trying to disable some startup programs one by one (starting with the ones related to network (wired NIC, wireless NIC, any software about network or internet connection).
