I know almost nothing about networking but maybe someone can help me solve this problem.
Computer A is running a thing on port 4444
Computer B is running a thing on port 4444
If I am on computer A
- I can ping computer B (both by IP address and name)
- I can remote into computer B
- I cannot open http://computerB.domain.com:4444/service !!!
However, if I am remoted into computer B, I can open everything just fine on that machine (the service running on computer A, and computer B, ping successfully, whatever).
I have disabled the firewall on both computers, but must be getting blocked by something else. Any ideas?
