I have upgraded my server from a windows 8 machine to a windows 10 machine and the other machines are windows 7. All was great for about three weeks, and then all of a sudden started getting error code 161 - i have uninstalled and reinstalled, turned off anti-virus, windows defender, set the UAC settings. but still the error persists. Am using Pastel Partner 12. Has anyone else had this problem and were able to resolve it. Please.
