Some clients collecting patches from the wrong path

Hi all,

I was checking my web filter and found a significant number of agents are going to the wrong path to collect their patches.  It seems to be a typo, as only the first letter of the address is missing

I.e.

http://RCE-LD-001/patch/windows6.1-kb947821-v31-x86.msu<- good

http://CE-LD-001/patch/windows6.1-kb947821-v31-x86.msu<- bad

Though I can't find where this has been set incorrectly.  It only a affects a few clients using different agent configurations, so it is difficult to determine where the problem is coming from.  I'm unable to find the bad path doing an Advanced Edit on my agent configurations

anyone know where I can find this setting?

thanks :-)
