Unable to connect to remote server Graham Fiddaman 5/28/2007 12:30:02 AM I am running SBS 2003 and have installed WSUS 3.0and have defined the synchronisation options to not use authentication to the firewall. I have ensured that ISA Server allows ports 80 and 443 When attempting synchronisation, an error occurs "- WebException : Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A socket operation was attempted from an unreachable host.

You need to make sure that ISA allows access for the "Local Host" on HTTP/HTTPS. -- Lawrence Garvin, M.S., MCTS, MCP Independent WSUS Evangelist MVP-Software Distribution (2005-2007) https://mvp.support.microsoft.com/profile=30E00990-8F1D-4774-BD62-D095EB07B36E Everything you need for WSUS is at http://technet2.microsoft.com/windowsserver/en/technologies/featured/wsus/default.mspx And, almost everything else is at http://wsusinfo.onsitechsolutions.com .....

Re: Unable to connect to remote server Graham Fiddaman 5/28/2007 7:00:01 AM Thanks for the hint, sadly I do not know enough about ISA to implement your suggestion. The IP filters concerned both allow the respective traffic on a port, with the local computer being "the default ip addresse(s) on the external interface" Is this not adequate? -- TasBuild Limited "Lawrence Garvin (MVP)" wrote: [Quoted Text] > "Graham Fiddaman" <GrahamFiddaman[ at ]discussions.microsoft.com> wrote in > message news:D242411D-D33C-4D8B-8467-D6B2CF15389F[ at ]microsoft.com... > >I am running SBS 2003 and have installed WSUS 3.0and have defined the > > synchronisation options to not use authentication to the firewall. > > I have ensured that ISA Server allows ports 80 and 443 > > > > When attempting synchronisation, an error occurs "- > > > > WebException : Unable to connect to the remote server ---> > > System.Net.Sockets.SocketException: A socket operation was attempted from > > an > > unreachable host. > > You need to make sure that ISA allows access for the "Local Host" on > HTTP/HTTPS. > > -- > Lawrence Garvin, M.S., MCTS, MCP > Independent WSUS Evangelist > MVP-Software Distribution (2005-2007) > https://mvp.support.microsoft.com/profile=30E00990-8F1D-4774-BD62-D095EB07B36E > > Everything you need for WSUS is at > http://technet2.microsoft.com/windowsserver/en/technologies/featured/wsus/default.mspx > > And, almost everything else is at > http://wsusinfo.onsitechsolutions.com > ..... > > >

No. In the setup for the access rule, on the "From" tab, add the network called "Local Host". -- Lawrence Garvin, M.S., MCTS, MCP Independent WSUS Evangelist MVP-Software Distribution (2005-2007) https://mvp.support.microsoft.com/profile=30E00990-8F1D-4774-BD62-D095EB07B36E Everything you need for WSUS is at http://technet2.microsoft.com/windowsserver/en/technologies/featured/wsus/default.mspx And, almost everything else is at http://wsusinfo.onsitechsolutions.com .....

Re: Unable to connect to remote server Graham Fiddaman 5/28/2007 11:41:00 PM Sorry Lawrence, but I think you may be talking about a later version of ISA. We are running ISA Server 2000 (from SBS2003 SP1 not R2 version). I cannot find any possible "From" tabs in Access Rules, because I can't find "Access Rules" Graham TasBuild Limited "Lawrence Garvin (MVP)" wrote: [Quoted Text] > "Graham Fiddaman" <GrahamFiddaman[ at ]discussions.microsoft.com> wrote in > message news:F9FF430C-6FDB-437B-8780-F6C62F5EE592[ at ]microsoft.com... > > Thanks for the hint, sadly I do not know enough about ISA to implement > > your > > suggestion. > > The IP filters concerned both allow the respective traffic on a port, with > > the local computer being "the default ip addresse(s) on the external > > interface" > > Is this not adequate? > > No. > > In the setup for the access rule, on the "From" tab, add the network called > "Local Host". > > -- > Lawrence Garvin, M.S., MCTS, MCP > Independent WSUS Evangelist > MVP-Software Distribution (2005-2007) > https://mvp.support.microsoft.com/profile=30E00990-8F1D-4774-BD62-D095EB07B36E > > Everything you need for WSUS is at > http://technet2.microsoft.com/windowsserver/en/technologies/featured/wsus/default.mspx > > And, almost everything else is at > http://wsusinfo.onsitechsolutions.com > ..... > > > >

[a] SBS2003 SP1 included an upgrade to ISA 2004. You probably should install it, since ISA 2000 is no longer a supported product. (Unless you've installed ISA 2000 on SBS2003 =Standard= Edition.) [b] The requirements are the same for both versions. The "ISA Server" (which in this case is also the SBS server) is blocked from all outbound access unless you explicitly give it access. > I cannot > find any possible "From" tabs in Access Rules, because I can't find > "Access > Rules" But you are correct in that the instructions I gave you are for ISA 2004, and will be useless on an ISA 2000 system. -- Lawrence Garvin, M.S., MCTS, MCP Independent WSUS Evangelist MVP-Software Distribution (2005-2007) https://mvp.support.microsoft.com/profile=30E00990-8F1D-4774-BD62-D095EB07B36E Everything you need for WSUS is at http://technet2.microsoft.com/windowsserver/en/technologies/featured/wsus/default.mspx And, almost everything else is at http://wsusinfo.onsitechsolutions.com .....
