One of our user (iFolder 3 client on Windows XP SP3) is getting the error "The request failed with HTTP status 404: Not Found." when she starts iFolder. This isn't happening with any other users.

The error pops up when iFolder starts and within the client afterward with every operation (opening accounts, viewing ifolders, etc).

This seems to start to happen (although not 100% confirmed) when she connects to new networks, for example wifi networks while travelling or switching from lan to wifi at work.

The only thing we've been able to do to fix this is to rename the simias folder under Documents and Settings\Username\Local Settings\Application Data. Reconnect to the iFolder server and reconnect to all the iFolders and resync.

I've checked the Windows Firewall logs, nothing there, the Simias log (also changed log level from INFO to DEBUG in the xml file) under the simias directory isn't even touched when this is happening, and neither are other files thereunder (maybe a clue?).

Any help is appreciated.

Thanks in advance,
