We have a Windows Server 2008 machine where we publish our asp.net web site. Recently, we noticed odd problems with the site after publishing, and traced it down to the \bin directory of the website being empty. It appears that any time a binary file (.dll/.exe) is remotely copied to that machine, the file is deleted shortly afterwards.
This is happening anytime files are copied through the domain path to the box (eg \machinename\inetpub\wwwroot\website). Using Remote Desktop access to the box and then copying files while logged into the machine works fine.
I've use Process Monitor, Process Explorer, and browsed both the event logs and the virus scanner logs extensively, and can find no evidence of these deletions. I have no idea why this happening or what might even be the cause. Does anyone have experience with this or some idea of what I might do to track this issue down?
