Hi Bill,
Which specific IPCC flavor are you running?
* For IPCC Express Servers (assuming you are running a version of IPCC express that is running on Windows 2000):
The OS patches for servers running CUCCX on windows 2000, the same OS patches applied to CUCM will apply. The following page lists the OS patches, and it looks like the latest one is OS 2000.4(5b)_SR8. In general, Cisco recommends that you keep up to date with the patches posted here, so a maintenance window every month or every couple of months may be a good idea.

* For IPCC/ICM Servers:
Cisco assesses, and where deemed appropriate, validates the Microsoft security patches along with any workarounds for the problems found. Cisco recommends that Contact Center customers separately assess all security patches released by Microsoft and install those deemed appropriate for their environments.
For ICM products, updates about Microsoft patches have historically been provided via Field Notices.
http://www.cisco.com/en/US/products/sw/custcosw/ps1973/prod_field_notices_list.html
Notice that the last Field Notice published was in April. Starting in May 2008, the monthly Field Notices responding to the Microsoft security patches have been migrated to the IntelliShield Event Response Microsoft Security Bulletin link on the Security Center. Visit www.cisco.com/security then click on IntelliShield Event Responses link under Technical Resources section.
You can us with RSS feeds to receive updates as needed.
These bulletins and updates are an informational service, assuring compatibility. You may still install patches that have been categorzed by Microsoft as Critical without waiting for the bulletin from Cisco.
Hope this helps.
Regards,
Michael.
