Group Policy Pref - Mapped Drives Not Applying to One User

Question

Hi All,
I’m new to this list, so please excuse any etiquette slip ups.  
I have three users at a site. All their machines are running Windows XP Service Pack 3 and have client side extensions installed. I created a group policy to map their default drives using GP User Preferences.
Each of the drives is set to "update".
As an example of the policy created XML is as follows:
<Drive clsid="{935D1B74-9CB8-4e3c-9914-7DD559B7A417}" name="H:" status="H:"
image="2" changed="2009-11-25 05:13:58"
uid="{8A44D2F4-AAE5-4F43-AEEC-D36F08EA619C}" desc="Maps the users H drive to
ServerName\users$\%username%" bypassErrors="1"><Properties action="U"
thisDrive="NOCHANGE" allDrives="NOCHANGE" userName=""
path="\\ServerName\users$\%username%" label="Home (ServerName)"
persistent="1" useLetter="1" letter="H"/></Drive>
and
<Drive clsid="{935D1B74-9CB8-4e3c-9914-7DD559B7A417}" name="J:" status="J:"
image="0" changed="2009-11-30 03:52:58"
uid="{535CD462-A45D-4363-ADA1-2316D5ECC703}" desc="Maps J drive for users to
\\ServerName\apps" bypassErrors="1"><Properties action="C"
thisDrive="NOCHANGE" allDrives="NOCHANGE" userName=""
path="\\ServerName\Apps" label="Apps (ServerName)" persistent="1"
useLetter="1" letter="J"/></Drive>
The group policy is applied to an OU for that site. 
All three users are in the same OU.
All three users are also in the same “xxsitecode Users” group.
2 of the users log into their pc and get the mapped drives with no issue, but one user doesn’t.
There are no other login scripts and the user has no manually mapped drives.
He does have a H drive mapped using the profile field in his AD object as a temp measure. But every 90 mins any other manually mapped drives are removed by the policy.
We don’t use roaming profiles
To trouble shoot I have tried
-    Reinstalling client side extensions
-    Re-joining the pc to the domain
-    Running gpupdate from the command prompt to see if any event logs are generated (none are)
-    Manually mapping the drives to make sure there is network access etc – I can manually map them/he can access them.
-    Creating the user a new account, when he logs in using that account he gets his mapped drives on all PC’s
-    Getting the user to log into a different pc, when he does this he doesn’t get his drives – so it’s not his machine or profile
-    Manually checking the security on the user object in AD against one of the users who gets their drives mapped
I'm sure the GP is fine because it works for two other users and the testing isolates his user account as the issue.
The Policy I’m having issues with is xxxx Mapped Drives/ Printers
I have posted this issue on the tech net GP discussion groups page, but haven’t had any replies.
Any suggestions would be appreciated.

What's interesting is that I applied a new GP to users - it has one policy setting and one preferences setting. He only gets the policy setting.. aka he gets the wallpaper but not the homepage.
Also, Jorke asked me to post the gpresult /z .
