Hey,
vsdatant.sys is a zonealarm file. That file comes preloaded on Dell
computers, along with other computers. Dell used to come with Zonealarm on
it, but when they discontinued using zonealarm they DID NOT remove the old
versions of the programs and some other programs with SP2 look for that file
and its the old version.
What I had to do is install Zonealarm trial version with the updated
version, copy that file vsdatant.sys to network or cd or floppy, then i
uninstalled zonealarm with all regiestry entries! Be carefule Mcafee and
other virus programs along with uninstalling zone alarm puts old version back
on. When this happens just copy the new version of that file you copied and
overwrite the old one and it fixes the problem. No reboot necessary.
