1. On the SBS server, open Windows Explorer and go to C:\Program
Files\Microsoft Windows Small Business
Server\ClientSetup\Clients\response\<clientcomputer>.
2. Open the apps.dat with Notepad. This is actually an XML file.
3. Find the app id "{F28193FE-08F8-4eae-B714-D425838F46FE}", then note down
the value of the associated attribute "refcount".
4. On the Windows XP client, click Start, click Run, type "regedit" and
click OK.
5. Locate the registry key
HKLM\Software\Microsoft\SmallBusinessServer\ClientSetup, double-click
{F28193FE-08F8-4eae-B714-D425838F46FE} in the right pane, and change the
data to the value of "refcount" that we get in step 3.
If the registry value {F28193FE-08F8-4eae-B714-D425838F46FE} doesn't exist,
manually create it:
Value name: {F28193FE-08F8-4eae-B714-D425838F46FE}
Value type: REG_DWORD
Value data: The value of "refcount"
