I've never tried to install Workstation on this type of server. I do know, however, that while installing NT server on systems with a lot of RAM, I got blue screen errors. To resolve the errors, I removed most of the ram ...leaving the system with like 256MB's...and then installed Windows NT server. I found in technet that SP1 can have problems with large amounts of memory. After the OS installation was complete, I upgraded to the latest service pack and install the rest of the RAM. Then system ran fine after that.
Hope this helps. Joseph L. Poandl
