MDAC service pack for NT

Hi Does microsoft provide DCOM and MDAC service packs for NT.Where can i get this service pack from if available.We have a applcation in VB 6 which uses ADO and MS SQL server.Our install shield works properly on windows 95 and 98 after running DCOM95/DCOM98 and then MDAC service pack.
But it fails to insatll on windows NT server.

Appreciate it if anybody could reply to this ASAP

Hello,
>>DCOM 95/98 does not work on Windows NT. Windows NT can support DCOM if you install Windows NT service pack 2 or later.
>>MDAC can work properly on both Windows 9X as well as Windows NT. You can get the lasted MDAC at microsoft site or in Visual Studio 98 and some other product of Microsoft. The lasted version of MDAC, I know is MDAC 2.5 in windows 2000. In windows NT and windows 9x, MDAC 2.1 is the lasted version.

Bye.
