Cristian Croitoru asked: MIIS 2003 can be installed (AFAIK) only on Enterprise version of W2K3; apparently Service Pack was supposed to enable installation on the standard server (why on earth there was a restriction at the beginning I would not have a clue). However I could not figure out how to install the MIIS 2003 and, then apply the SP to be able to install on Standard :-) :-) Well Cristian, Its confirmed. Service Pack 1 for MIIS 2003 has support for SQL Server 2000 Standard but still requires Windows Server 2003 Enterprise Edition.
Heres a link to MIIS Service Pack 1 and here to the System Requirements
Did you know that theres also a Resource Toolkit been released?
