SignTool hangs on main development computer

Question

All of the sudden, whenever I try to use SignCode on my main release computer to sign a binary, SignCode simply hangs until I kill it with Task Manager. No error messages are displayed. After some investigation, I've discovered the following:

* If I remove the timestamp switch from the command line, it works fine without hanging. 
* I can sign just fine from other computers, even with the timestamp switch.

So, it seems the timestamp call is causing problems on my release computer. Any ideas what could be causing this, or how I could troubleshoot? 

Thanks,
Sean

Answer 1

Maybe it waits for an external web site to provide timestamp (unless you're running your own service). Getting a stack trace while it's waiting may be helpful.

Answer 2

Yes, signtool was hanging on the network call, yet other apps could use the network just fine (e.g., I submitted the post above on the same computer where this problem was happening). 

Turns out, the problem was that I have two network adapters on this computer, and one of them had lost a network connection. Whereas my browser seemed to find and use the connected adapter, signtool was plugging away using the disconnected one. Once the connection was reestablished, the problem went away.
