But at second time login it ask again my UserName, Password.Here the problem is, at subcriber when i click View Subscrption status,"Specified File not found",error occured. At second time I try with address https://MyServer.dyndns.biz/TestPublication/replisapi.dll, and this time also dignosis window is successful, but it ask me UserName, Password if i enter dignosis mode again. Here the problem is error "The Proxy Auto-configuration URL was not found.", comes.
