Lars:

While your situation sounds horrible I have a hard time believing it is
the result of OpenAFS itself being uninstalled.  If that were the case I
would run into the problem on a consistent basis as I switch between
release series.  OpenAFS does not add itself as a dependency for other
services.

My guess is that one of two things are true:

a. the local administrator account has somehow obtained a dependency on
the \\AFS name space perhaps with an auto-run or other and as a result
will not start because after OpenAFS is removed there is no method of
accessing the dependency.

b. your machines have a rootkit or other damage and the removal of
OpenAFS is triggering bad behavior.

The 1.5 series does not have any kernel component and is not capable of
altering the role of administrative bits.

I would start by examining the registry for dependencies on \\AFS.  For
example, are there any system drive mappings to \\AFS that would be
persisted?  Any service application paths that refer to \\AFS or a
mapped drive letter?  Etc.
