Configuration:
Digital PC PC3100.5100,3500,5510 running Win95 and an Iomega ZIP drive installed.


Problem:
The system will hang while trying to autorun a zip disk
Additionally if a CDROM drive is also installed, the system will hang when trying to autorun the CD.

Solution:
Microsoft has released the fix which contains:

Esdi_506.pdr v4.00.116
Voltrack.vxd v4.00.954 


Notes:
Additionally this fixes a problem with occasional systems hangs while accessing data from UDMA HDD's.

We are currently FISing QFE 513 which is an earlier version of Esdi_506.pdr. This fixed the UDMA drive hang problem.
Our recommedation is for users with Iomega ZIP drive to install this fix.
