I seem to be having a strange connectivity problem at a client site where we are hosting an FTP site in IIS. We also allow remote desktop connections to this server for troubleshooting purposes.
Whenever the client is experiencing these connectivity problems we are unable to connect to the ftp site or remote desktop. The issue seems to be resolved if the client logs into the server and navigates to a website like google in Internet Explorer.
Could this be some kind of dns issue or something? Looking for some suggestions.
Edit
The power scheme on the server is set to "Always On". When I say the "client" logs into the server I mean they remote desktop on to the server from a workstation. It appears that they did report an instance of where they remoted on to the server and communications began to start working again but soon failed so this may not be related. They've also seen the same things from launching IE and navigating to a website. This is a production server that has been there for awhile and we just started seeing these problems recently.
