Facing a very strange problem from yesterday, suddenly loss connectivity with FTP site with no apparent changes to the PCs and or Firewall settings. Well the strange part is that I can successfully access and upload files from home. First thought the error is on the hosting side and submit a remedy ticket but was told that the possibility is very low since I am able to access the FTP site from home. I also contacted the ISP (Comcast) and the support tech reviewed the Business Gateway Router settings which were also deemed OK...I also did uninstall Norton Security thinking it might be the culprit but the issue remain the same i.e. not able to connect/access FTP site from Office/Work network. Any help and guidance will be appreciated.
