Our customers have a folder that contains a mixture of .doc and .docx files. On one customer's Server 2008 R2 Remote Desktop sessions, the CMD Prompt command 'dir *.doc' only returns .doc files. On all of our test systems and all of our other customers' systems, this one command returns the .doc and .docx files.
Our actual issue is more complex than this, but it boils down to needing to change this one customer's system so that the one instruction returns both file types.
I can't find an environment variable that controls this. Is there some Group Policy setting?
