Question

I have a DLL registered on 3 different servers, one development and two production. This post helped registering it on the servers.

No we are trying to put the site on a second production server so that we can load balance it. On development and one of the production servers, i can create my object and utilize it just fine. On the second production server, it gives me:

Microsoft JScript runtime error ‘800a01ad’
Automation server can’t create object
/code/FileSystem.asp, line 459

Line 459 in this case is:

var oFSO = Server.CreateObject("Hydro.Comm.FileSystem");

Both production servers are Windows Server 2008 with latest patches installed. I am confused as to why the second server is not registering this DLL properly.

We followed the following steps to register the DLL on each server:

• We needed to install the windows sdk for .net framework 4
  http://www.microsoft.com/download/en/confirmation.aspx?id=8279

• Then we needed to add the assembly to the GAC:

  C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\NETFX 4.0 Tools>gacutil /i 
  C:\Windows\Microsoft.NET\Framework\v4.0.30319\HydroComFileSystem.dll
  

• Then we needed to register the assembly with regasm:

  regasm /tlb HydroComFileSystem.dll
  

Thanks for looking.
