Windows.


CDR4VSD
I upgraded my machine at work to a shiny new 2.5Ghz Pentium 4, installed Windows 2000, spent a week installing all sorts of software, and then finally totally screwed it up by installing Adaptec/Roxio Easy CD creator 3.5c. The symptom: when booting, the PC will get to the booting Windows 2000 screen (with the progress bar and rotating blue band) and will just SIT THERE forever. This is because (I think) Easy CD creator creates a service, CDR4VSD, that is incompatible with Windows 2000 and stops the booting process cold.

How to fix: Boot from the Windows 2000 CD, use the recovery console, verify that CDR4VSD is installed by using LISTSVC, and then use DISABLE CDR4VSD to disable the service. Now reboot and uninstall Adaptec Easy CD creator! Thanks to deja.com for getting me out of this mess. Note that apparently version 4.0 also has this problem.

Microsoft has a knowledge base article on this: Q237468

Here's Adaptec's info:

      Hello from Adaptec,

      This is in regards to the issue you are having with windows 2000
and not being able to boot after installation of Easy CD Creator.

      What you need to do is boot the system into "Last Known Good." 
Once there you will then need to go the the "Start" button and then to
the "Search" option.  From here you will need to do a search for two
files, the first one being "CDR4DLL.DLL" once you have found that
rightclick on it and select the option to rename.  Change the name to
"CDR4DLL.OLD"  The next file you will need to search for is
"CDR4VSD.SYS" once you have found this file rightclick on it and do
the
rename option again and change its name to "CDR4VSD.OLD"

      Once this is done restart the computer normally and everything
should work correctly for you.  If you start the program and have
errors
simply uninstall our software and reinstall it and everything should
then work correctly.

      Thank you for using Adaptec's Ask Us
