software update giving error - NSURLErrorDomain error - 1100

[ironjackflint]

I'm using Netsus and it's not picking up any updates. I'm getting this error instead. I'm dumped the prefs and re-pointeed at Apple and the updates appear. So far I've only tested this with 10.8 machines so it might be an OS thing but if anyone else has seen this it would be great if you could shed some light!?

We've seen this problem on some of our 10.8 machine only... it appears to be 10.8 specific. We point to an internal SUS (on X serves). The problem seemed sporadic and was sometimes resolved by changing the machine's proxy settings to not use "Auto Detect" (we're running through a proxy).
