SUMMARY
Small Business Server (SBS) includes the standard Microsoft Windows NT Disk Administrator tool. You can use this tool to change the drive letter of the boot partition, but doing so can cause problems. If SBS is installed on drive C and you change the drive letter for drive C to some other letter, several services in SBS stop working, although the operating system itself does start.



MORE INFORMATION
The following services stop working when you change the drive letter as described above:

The MSDTC Service

The IP Filter Driver service

The Proxy Alert Notification service

The Microsoft Proxy Server Administration service

The Microsoft Search service

The Microsoft SQL Main Server service

The Protected Storage service

The World Wide Web (WWW) Publishing service

The Microsoft Winsock Proxy service

The IIS Admin Service service

The Microsoft Exchange System Attendant service

The Protected Storage service

The Microsoft Exchange Directory service

The Microsoft Exchange Information Store service

The Microsoft Exchange Message Transfer Agent service

The Microsoft Exchange Event service

To resolve this issue, change the drive's letter from the current drive letter back to the original letter, and then restart the computer.

NOTE: Programs that are hard-coded to use drive C instead of the Expand_SZ %SystemRoot% parameter also do not work when you change the drive letter. This behavior applies to installed client programs as well.
