Communication tab does not show up in ADU&C when OCS 2007 is installed on Windows 64-bit

November 8, 2007

in Microsoft, OCS

Issue:  Office Communication Server 2007 is not a 64-bit program (It will install the in \Program Files (x86) folder) so when you try to enable a user for OCS using the DSA.MSC utility (aka ADU&C) the Communications tab does not appear. 

Reason:  The OCS extensions are 32-bit and do not load when running the MMC in the native 64-bit.

Workaround:  Run the MMC in 32-bit mode.
