Hi, I have a new SBS 2011 standard server but seem to have firewall \ access issues. 5-6 Workstations can access a sql server without any problems but a new PC can't. I have reset the PC to factory defaults but it still can't access. I have run a port scanner and the only port it sees as open is port 137. The server has a few failed updates due to a power failure !

Help, Peter.

If all machines are not able to access that means problem with server. but in your case few machines are working fine.. only newly added machines are not able to connect.

so you need to check it out new machine .. isn t?

Yes, but connecting to Sql server works on old PCs but can't telnet to the server, weird. Also other problems with running some apps off the server which also point to blocked ports.

No, old PCs can, new ones cant. There is also a couple of apps on the Server that should connect to sql server but don't work on old or new !
