IIS 6.0 - ASP legacy apps and Windows 64 bit

1 New Member
History: We have some legacy applications developed under ASP that make call to OLEDB and such. These apps were hosted on a complete 32 bit achitecture - IIS 60 running on Windows 2003 32 bit.

We wish to move these ASP (Not asp.net) applications to Windows 2003 64 bit.

Having setup a 2003 64 bit server - which is now pure 64 proceeded to ...

Setup the legacy application under IIS 6.0 64 bit ... and was getting the dreaded Provider error -- something about it not like the DB connect - tried Provider=SQLOLE DB, PRovider=SQLNCL I all to no avail. DB connections are setup via the global.asa file.

K, so now apps are not working on 64 bit or they may perhaps with some changes to the DB connect strings but I'm no DBA and exhausted all my options I could research the net for.

So ... went onward to configuring the 64 bit to run IIS 6.0 in 32 bit mode, installed .net 1.1 and .net 2.x 32 bit - uninstalled .net 2.X 64 bit now here is the PROBLEM ...

It states that when IIS 6.0 is in 32bit mode you cannot run both 32 bit and 64 bit dlls at the same time on same server ...

Well, ASP configured on the box is set to use the 64bit ASP which would not work well with IIS 6.0 expecting 32 bit??

Had even tried changing ALL SYSTEM32 64bit script dlls to point to the SYSWOW64 scipt dlls - no go!

Any ideas on getting ASP to run via 32 bit DLL so that it will use the necessary DB drivers located in the SYSWOW64 directory?
