The remote procedure call failed and did not execute. The sites were connected using MikroTik routers at both ends using a PPTP VPN with no NAT between the two sites. Temporarily one of the sites was running on a 4G connection and the other site was on Telstra Business ADSL.
I can't seem to open any folder using Explorer in Windows 7 RC b7100, as it fails with the above error. This happened after Explorer stopped picking up metadata on files, and so I killed and restarted explorer using Task Manager. Files and folders on my Desktop still show up, and files still open in their respective applications, but folders won't show, as with the error. Happens with any local folder. I can't find anything on Google. I haven't touched any Explorer settings, and I'm not interested in an Explorer alternative. I can restart, but this has happened once before, so I'm thinking it'll happen again after a restart. Anyone have any more permanent ideas?
