If you are finding the login process is slow, or longer than usual, then this may well be caused by a resource mapping issue when the PNshell process runs. If PNshell is trying to map a printer or drive mapping that fails then there may be a timeout before the script continues.
The log file created by the steps shown in SOL92116 will be created in the home drive & path of the user who logs in. For example if my Homedrive were=H: and the Homepath=\users\david then the log file will be located at H:\users\david\pnshell.log
I will update the solution to include this information.
