Broken IWAM account

We use a W2K domain controller with a policy in effect that renames the administrator account. This does all the desired things however, if you run the TSAC client on IIS it all works fine until you reboot – after a reboot the TSAC webservices willnot run as the user account for IWAM gets out of sync – you need to run the synciwam.vbs script to get every thing back into shape.

Is this a natural outcome of remaping the admin account or just a bug?

anyone any ideas?
