Hello Micheal,

These are the instruction for windows 2003. but i have to use the ktpass on windows 2008.

The syntax of ktpass is different in win2008.

Can you just type the syntax of ktpass for me for windows 2008

after the "-mapuser" switch is the username for the adsso account. although the example gives it in the following format:

"... -mapuser username..."

i've had to use the following format to get it to work:

"... -mapuser domain\username..."

This was for an error that said it couldn't find the domain or something like that.

You do not have to give that as domain\username, since you are providing that information after the -princ switch.

Check it and let me know.

Man it was holiday for 2 days. I will be trying on Monday.

However can you write the ktpass command syntax for me for Windows 2008. I think that there is a difference between the the syntax of windows 2003 and 2008.

Hello Sure,

Which win OS you were using. Are you sure it was windows 2008.
