SYMPTOMS
When you run the Microsoft Office Live Communications Server 2003 Setup program to install a Live Communications Server 2003 home server, you receive an error message that is similar to one of the following:

Error 27780: Unknown error occurred while creating RTC Server database.

An unexpected error occurred while checking for necessary space for database files. Please try again.

Note You receive these error messages when you select the location to store the Live Communications Server 2003 database files, or when the Setup program tries to create the database files.



CAUSE
This issue occurs if the Microsoft SQL Server 2000 Desktop Engine (MSDE) installation does not register the Sqldmo.dll file correctly. This issue may occur if both of the following conditions are true:
 * You remove MSDE.
 * You run the Live Communications Server 2003 Setup program to install Live Communications Server 2003.



RESOLUTION
To resolve this issue, use one of the following methods, depending on whether MSDE is installed:

Method 1: Reinstall MSDE
If MSDE is not installed, reinstall it and then reinstall Live Communications Server 2003.

Method 2: Register Sqldmo.dll
If MSDE is installed, register the Sqldmo.dll file and then reinstall Live Communications Server 2003. To register the Sqldmo.dll file, follow these steps:
 * 1) Click Start, click Run, and then type regsvr32.exe sqldmo.dll.
 * 2) Click OK, and then click OK again.

Method 3: Make sure that %temp% has no spaces
Run the SET command at a command prompt. Make sure that both the TEMP variable and the TMP variable are set to 8.3 format. In 8.3 format, there are no spaces in the name. To change the TEMP variable to 8.3 format, run SET TEMP=C:\TEMP, where C:\TEMP is a folder that exists on the computer. To change the TMP variable to 8.3 format, run SET TMP=C:\TMP, where C:\TMP is a folder that exists on the computer.



MORE INFORMATION
The same error will occur if the Oledb32.dll is not the original release version of Microsoft Windows Server 2003. If you copy the correct version from another Windows Server 2003-based computer, the install will complete.
