Core Issue

The use of the web interface on a Cisco Unity 4.2.1 with failover causes a prompt to appear in the Microsoft Internet Information Services (IIS) authentication window. After this window appears, the page goes blank and freezes. When this happens, use Virtual Network Computing (VNC) in order to connect to the Cisco Unity server and reset the IIS. This is the only way to re-enable the web interface. The IIS reset fixes the issue for a while.


This issue is documented in Cisco bug ID CSCsf26335.

In order to workaround this issue, complete these steps:

  1. Restart the IIS World Wide Web Publishing Service through the Services Microsoft ManageMMC snap-in.

  2. If the inetinfo.exe file does not restart with that method, use kill.exe in the commserver directory in order to kill the process.

    Note: These files are located in c:\commserver\inetinfo.exe and c:\commserver\kill.exe, respectively.

  3. It should automatically restart, but if it does not, start the World Wide Web Publishing Service through the Services MMC snap-in.

In order to resolve this issue, install one of these Engineering Special (ES) patches on the Cisco Unity server:
