I was having problems with one user not being able to access the companyweb remotely although everyone else was working fine. I checked all permissions and all looked fine so I decided maybe something had become corrupt and deleted the user from the site admin user list, all seemed to go fine. I restarted IIS using IISRESET and then tried to re-add the user back into the site again. Unfortunately I am unable to complete the task as I keep getting 'Can not add the user because a user with that name already exists.'
Please can someone shed any light on this as the user does not show on any of the user lists within companyweb!!
