I have an form on a server running IIS 7.5 that allows the user to attach multiple files. However I receive an error when trying to attach .docx, .pptx, and .xlsx files.
I have verified the correct MIME types are set on the server. ie:
There are no errors appearing in the event viewer or the IIS logs, but I did find one in HTTPERR:
HTTP/1.1 POST /BLA/Primary/inc_attachFile.asp 400 25 BadRequest BLA HTTP/1.1 POST /BLA/Primary/inc_attachFile.asp 400 25 Connection_Dropped BLA
The odd thing is that i can successfully attach a
.docx while in IE on the server itself, but when I try on a workstation I get the error. I've tried adding additional rights to several accounts on the folder but it made no difference.
Any help would be greatly appreciated.
