Other machines in the hierarchy are using the SUP without issue as we move them into the SCCM environment. Note that this server was managed by another WSUS server for its own updates.
I have performed the following actions on the server itself:
Reset SoftwareDistribution folder
Confirmed that there is no proxy settings via netsh winhttp show proxy
Enforced no proxy setting using bitsadmin for local system/network service
Tried re-installing the agent using /wuforce switch
So as it turns out it was a legacy ISA web filter solution that was causing this issue; I ran a WireShark trace and saw there were the following errors every time I ran an update scan/tried to install a detected update:
502 Proxy Error. The specified Secure Sockets Layer (SSL) port is not allowed. ISA Server is not configured to allow SSL requests from this port.
I found that there is a legacy 'wpad' entry in DNS that machines are picking up and auto-configuring themselves with; despite ensuring that netsh winhttp proxy was set to direct, and using the bitsadmin tool I have disabled the proxy configuration.
We still need the DNS entry so the solution was to enable HTTPS on 8531 (ISA specific as it will only allow HTTPS traffic on port 443 by default) and create a rule to permit the access.
All of the affected clients (~75% of all COnfigMgr clients) sprang to life the following day.
