SFU hot fixes in email

Like any other Microsoft hot fix, you can also receive SFU hot fixes in your inbox - http://go.microsoft.com/?linkid=6294451

All you need is the KB article number which describes the fix you need. While we are talking about it, the following is also important to note -

"Hotfix Information

A Hotfix is a single package that includes one or more files that is used to address a very specific customer problem with a product. A supported Hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in the previous mentioned article. Only apply it to systems that are experiencing this specific problem. This Hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next service pack that contains this Hotfix."

Why am I talking about it here?
At first, it doesn't sound like has anything to do with SFU or UNIX Interoperability components shipped with Windows. But, then users who use these components know that hot fixes get them out of many problems. I am sure a lot of them would prefer getting the hot fix using this form instead opening a case.

Before you rush to request the latest and greatest fixes for SFU or R2 components - be informed that there are a few of them which have very specific prerequisites and if they are not fulfilled, you may run in to other issues. Read below to know about them -

KB913030 - Applies only to Services for UNIX 3.5
You can install this hot fix on any system that's running Interix Subsystem, Server for NIS or Password Synchronization. It doesn't create any problems but is mentioned here since it contains some stability and reliability update for Interix subsystem and some utilities. You should install this fix before you install any other Interix subsystem hot fix which is newer than this one.

KB921599 - Applies only to Services for UNIX 3.5
Many people get confused with the information in the Kb article. This hot fix again applies only to Services for UNIX 3.5 Server for NIS and Password Synchronization components. You need this hot fix only if you have added a Windows Server 2003 R2 DC (or upgraded one of the DCs to R2) AND have also installed Server for NIS Identity Management for UNIX (IdMU) component which comes with Windows Server 2003 R2.

Since IdMU components in R2 use RFC2307 schema classes and attributes, when you install these components in SFU 3.5 environment, the installation process upgrades all of the NIS objects (NIS Domains, maps, users, groups etc.) to use R2 schema enhancements. This breaks Services for UNIX 3.5 Server for NIS and Password Synchronization components since they use a different schema. Installing this hot fix updates the SFU 3.5 Server for NIS and Password Synchronizarion binaries to use RFC2307 classes and attributes and helps SFU 3.5 and R2 IdMU components to co-exist.

KB936529 - Applicable to Services for UNIX 3.5
The previous post talks about it. Windows Server 2003 Service Pack 2 installation breaks SFU 3.5 Interix Subsystem and Password Synchronization components and this hot fix helps you to undo that. This hot fix should not be installed on Windows Server 2003 R2 SP2 systems because if you are using Password Synchronization IdMU component, this hot fix replaces the pswdsync.dll file with the one meant for SFU 3.5. As a result, Password Synchronization stop working.
