I'm unable to print to a network printer. The firewall log shows that spoolsv.exe to the remote printer port is blocked because of an Invalid Checksum, it's coming from localhost(any).
I've tried searching the computer for all instances of spoolsv.exe and have added it to the checksum list in the firewall configuration, since the log doesn't tell me the file path of the specific application it blocked... I've also ensured that the LAN IP address of the printer is added to the trusted list.
Neither works - when I allow all traffic I can print without any problem, so the firewall is definitely the culprit here.
I'd be grateful for any suggestions?
