----------------------------------------------------------- From: AnupPS Message 1 in Discussion Dear Friends, I had a strange problem few days back. Due to power failure and a following backup-power failure, most of our servers got down. All the client machines are in a NT-domain called "CLT" and the developers are in a seperate NT-domain called "DVP". The servers are in a seperate domain "SRV" The client and server applications use .NET remoting to communicate (at server port 20004). After power supply was restored, every server was started according to recovery plan. I checked that the remoting clients are working fine from developer domain "DVP" and gave all the others clients in "CLT" a go ahead that they could resume work. To my surprise, it wasnt working there. I tried ping and telnet to the server ports. Both worked fine. Means that the TCP-IP connection was working perfectly. But the client applications were not connecting, giving an error "HTTP Web-proxy requires authentication......." Though we have configurable-proxy facilities in our client applications, we never used those. After an hour of debugging on the client machines, I found that the error was created by the underlying classes-methods of SOAP request send/receive. We have an ISA server is used to interconnect the different intranets/domains in our organization and also give Internet access. It somehow managed to stand in the power failure. It was just a hunch that I asked the system admin's to restart the Microsoft ISA server services (not server) itself . Surprisingly again, everything started working fine now. The problem is ::: What caused the failure for the remoting clients only when TCPIP was perfectly working. If anybody has a slightest idea of what could have occured, please let me know. Any questions ...plz ask. Thanks, Anup Shinde. ----------------------------------------------------------- To stop getting this e-mail, or change how often it arrives, go to your E-mail Settings. http://groups.msn.com/bdotnet/_emailsettings.msnw Need help?
