Hello mclemson,i think you misunderstand my discription.
The truth is that, one site server(named A) downloads pmimport.cab and other cabs and bulletins from Symantec, and other site servers download pmimport.cab and other cabs and bulletins from A.
Now every site server can download cabs successfully, but when download bulletins, it maybe fail, it shows me that the GUID ({2jej-9kls-a093-jdks-oq9} for example) doen't exist.
I find that the same bullin in different site server has different GUID, when the GUID is different from A, it must be fail to download.
Can you understand me? My English is very poor.
But I need the answer, I need to know how to resolve it.
