User can't scan to file over the network

Hopefully someone may be able to give me some direction, since this has got me pulling my hair out.

I do IT for a small office environment, and all the users utilize a Ricoh MFP to scan and push the scanned file to a share folder on that user's computer over the network. One of the users had an unexpected shutdown, and since then she has not been able to use this feature. From what I could tell, the scanner is not able to communicate with the share folder and the scan jobs for her get stuck in the scanner's queue. All other users have no issue with scanning to their own share folder on their computer - just her.

I have verified that the folder has the proper permissions set up; I've tried creating another share folder somewhere on her machine; I've tried disabling the firewall and the antivirus; I've tried giving the scanner different log-on credentials (since it appears the scanner has to have actual user credentials to access the computer). Nothing that I have tried has gotten me any closer to an answer. I know that it has to do with her computer being locked down in some regard - she is the only user affected and there is another Ricoh MFP that we tested and it behaves the same way.

Does anybody have any more ideas? I'm running out of things to try!
