Question : SCCM 2007 Constant Despooler error 4406

Good morning,

I have just installed a SCCM 2007 server and have begun configuring my secondary sites. I had just done an install at our sister company a few weeks back and it went flawless, but not so much this time around. Many of my secondary sites are CONSTANTLY getting the following error:

SMS_DESPOOLER 4406: SMS Despooler received an instruction and package file from site XXX that contains either software distribution data or inter-site replication data, however either the signature on the package or the hash algorithm ID used for the signature is not valid, the despooler will delete the instruction and the package file.

On one secondary server last night alone it occured at 2:41AM, 4:02 AM, 5:17 AM, 6:17 AM, 9:17 AM etc. Another one had it occur at similar times...no 2:41 but 4:02 AM, 5:17, 6:17, 9:17.

Any idea what could be happening here? I have done many searches and not come up with much of anything. Thanks in advance.

Answer : SCCM 2007 Constant Despooler error 4406

Disabling secure key exchange requirements from the primary and all secondary site servers has resolved these errors, and in my case is safe as SCCM is only running internally within the network.
