Remote domain credentials for a share accepted from all but one user

We have a site with a VPN to a client network.  In order to transfer files, the client has shared a folder on their domain and set up an account, "CLIENTDOMAIN\ourcompany", to give us access.  We are able to access this folder from multiple computers on our domain by supplying these credentials when attempting to access the folder, but one specific user cannot access the folder with these credentials.  When the are input, the user dialogue simply reappears and we are unable to gain access.  My question is, why would one specific user on our domain be unable to access this remote share, while other users with the same rights (including a fresh copy of the user made in AD) can access it fine?

Any chance there is a saved credential on thier local machine to this share, with out of date creds?

control keymgr.dll

Run the above from a Run command, and see if there is anything listed...

I agree, even stranger is that running:

NET USE X: \\Server\Share /User:CLIENTDOMAIN\ourcompany password

manually will connect fine, but getting it to come up from explorer by navigating to the folder or by typing "\\Server\Share" into the run dialogue does not work. I consistently am not allowed access using the same credentials.

Wow, good call johnb.  I checked and there was an entry for "\\Server" there.  

Strangely, the credentials for this account never changed and this user was connecting fine until recently, but the stored credentials in the keymgr.dll entry were incorrect.  What determines an entry, simply checking the "remember this password" box?

Pretty much, once the flag to Save is checked, it writes it there..... I believe it should be saved after the connection attempt, not necessarily the connection success....
