Windows Server 2003 SP2 deleting browscap.ini?
There have been reports of Windows Server 2003 SP2 overwriting browscap.ini on machines with new versions of the file. If you have an updated browscap.ini, you should back up the file before installing SP2, and then copy it back after installing SP2. If you are arriving at this page because your browscap.ini was already deleted, I suggest downloading a fresh one from Gary Keith.

Update: dev team confirms that this is the behavior, and have raised a bug. In the meantime, you should also be able to find your old copy at %SystemDrive%\WINNT\$NtServicePackUninstall$\browscap.ini after installing.
