New computer and have BOINC up and running on a single identity in Win 7 but when I open BOINC in another identity it can't connect to the servers. Never had this problem with the old computer.

What am I failing to do?

The messages have varied a bit but today the message is that it can't connect and appears on top of the advanced view of BOINC. On my old computer I would choose run as administrator on the secondary identity and had no problem. This one seems to be a bit stubborn.

Thanks for any advice.

I believe that this is the connection between the BOINC Manager, BOINC_Mgr.exe, and the BOINC Daemon, BOINC.exe. Is there anything displayed in any of the tabs in the advanced view? If not, then this would confirm this.

The BOINC Manager communicates with the BOINC daemon by way of TCP port 31416. This means that your local firewall has to allow BOINC.exe to act as a server for port 31416 on either the local host only (for local control only) or the LAN (for control by other computers on the LAN). Some local firewalls also have outbound rules. If this is the case, you also have to allow BOINC_Mgr.exe, BOINC_Cmd.exe and BOINC.scr outbound access on port 31416.

There are two other possibilities:
1) BOINC.exe is not running. Please check task manager.

2) Some other program already has port 31416 allocated (usually malware).
Open a command prompt and type "netstat -ano" without the quotes.
You should see something like:
TCP 127.0.0.1:31416 0.0.0.0:0 LISTENING 14504

The 127.0.0.1 is the Local loop back address. :31416 is the port. LISTENING is the one that you want. You might also see ESTABLISHED as well. The last column is the process ID (in this case 14509). Look up the PID in task manager to see what process has the port open.

A question
When you installed BOINC did you tick the "allow all users" box (a Windows message), if you didn't then BOINC will only run properly when that user is logged on. Other users may get messages about not being able to connect, or not being able to run BOINC at all.

Yes I did tick the all user box.

I ran the statnet -ano and the port wasn't in use or allocated or anything.

Quite by accident I think I have found a software issue in which administrative rights are not being allowed on the secondary identity.

I am still checking and will reply in case someone else has this issue.

Thanks for the help.

Everything works normally now.

I must have changed something but I have no idea what it was.

One of the mysteries of the computer world.
