I prefer using 1 common version of kixtart in the netlogon but there are some costs. It tends to slow down execution. If any of your clients have a slow link to the logon server this could become an important issue.

In Jens' script, I think he created that file on the server & he uses it & the naming convention as a semi-automated way of keeping the local version of kixtart current.

As a side point - often you will find your particular problem is simular to other problems that have been discussed yet not exactly the same. Often a few modifications to the posted code is all you need to get it going. It was my thought that you should use what Jens did as a template. Read it & understand it fully & then modify it to suit your needs.
