Last week, I sent out a plea for help from a Fusion reader having problems with Windows 2002 SP4. You can read about the issue here:

https://www.nwfusion.com/newsletters/bug/2003/0707bug2.html

A potential solution has been submitted by reader Charles Olin:

Don’t know if the individual has tried uninstalling SP4 & uninstalling SP3, then just do a fresh install of SP4 only.  Now this would be dependant upon if the user had selected the option to pack up previous SP installation. Let me know if this helps the individual.  Without much more detail on if the individual had backed up SP installations and further information it’s really hard to pin point.

Hope that works. Thanks Charles for your help.

In this situation, GnuPG would not emit a warning when a low trust ID is used for encryption if that key also contains a trusted enough ID.” For more, go to:
