Windows 2003 SP1: Support Ends in Two Weeks (April 15, 2009)

Just following on from some Lifecycle-related musings.

24 months after SP2 was released, Windows 2003 SP1 will cease security update and hotfix support.

From the Lifecycle Supported Service Packs page:

Windows Server 2003 Service Pack 1 / 30-Mar-2005 / 14-Apr-2009

Windows Server 2003 Service Pack 2 / 13-Mar-2007 / Not Applicable
See Note
Support ends 24 months after the next service pack releases or at the end of the product’s support lifecycle, whichever comes first. For more information, please see the service pack support policy at

When you upgrade to SP2, it’s an excellent time to apply other updates too.

My suggestion would be to test installing everything up to this minute, using WSUS, SCCM, SMS or whatever, but if there’s one update I suggest you should apply after SP2, it’s 948496. That’s the Scalable Networking Pack disablement fix. (If you didn’t know you were using SNP under SP1, you don’t want it under SP2).

SMB/CIFS support for File:// URLs in CRL Distribution Points: Nup

According to Brian Komar, CDP and AIA extensions won’t work any more with file://\\server\share URLs as of Windows Vista SP1 / Windows Server 2008.

Note: With the release of Windows Vista Service Pack 1, support for Common Internet File System (CIFS) or Server Message Blocks (SMBs) through a File URL was dropped for AIA and CDP retrieval.

From Windows Server 2008 PKI and Certificate Security, page 245.

Why post it here? Because I couldn’t find this information on the interwebs, only in a book. I spent 20+ minutes looking!

A book. In this day and age!?

Aha! Here’s the KB article describing the change! 

(if like me you got hung up on SMB or CIFS being a keyword for the change, well, there ya go. I guess that file:// just implies whatever you’ve got going on in your redirector, so while SMB/CIFS might be most common in Windows networks, it could have been NCP/NFS/Whatever here.)

Hope that saves you some searching, future-Tristan.
