Installation issue: Authentication: AWS for Windows NTLM returns error

Question

We are rebuilding our STG with Plumtree 5.0.4. After I installed Optional Enterprise Web Components, the Authentication: AWS for Windows NTLM returns error. I am wondering if anyone has the similar experience and could help to fix the issue. I have located error with the virtual directory but unable to fix it.
<b>Symptons</b>
When try to access
http://servername/ntaws/RemoteSynchService.asp, got 404 page/folder not found error.
<b>Log Error:</b>
The message returned from the IIS creation of virtual directory ntaws on the Default Web Site
web site for D:\Program Files\plumtree\ptntaws\5.0\webapp\ntaws\www is:
<message>
Error
Error
</message>
<b>Solution Tried:</b>
1. Manually Create the virtual directory - didn't work
2. Reinstalled the Optionsal web service AWS portal, and re-migrate the ntaws.pte - didn't work.
I appreciate your help.
