Problem could be related to security programs, but I guess you probably configured it properly.
Can you try to start CnCNet on the other computer first and see if that works? The one starting CnCNet first will become the server.
If it doesn't help, try the latest version from here: http://downloads.cncnet.org/cncnet5.exe
Hi FunkyFr3sh, thanks for all the work done to support these games!
I didn't try cncnet until now. Thought it's just works online. I've been using the original game skirmish / lan interface from the beginning.
The cncnet UI has improvements like start locations and so on; I played some skirmish, however I couldn't get the lan server finding two computers connected with eachother, in a local network, without internet. This while the firewall rules were changed to allow it.
The mix with the ra1, ts and snow maps in d2k is kinda weird, I tend to keep the games separated.
I'll keep trying and if nothing works then I'll further look in the game exe for some tweak.
You didn't try CnCNet yet? Supports Online / LAN games with 2p VS 6 AI fine. There are also maps included where the 6 ai have preset alliances.
No need to change any files or download any mods, works out of the box
To add AI players on CnCNet use the button in the top right inside the game room
The Geocore Industry has a start date of 1800, which is why it pops up so early. The developers obviously intended for it just to be used in the campaigns, or to be manually placed down in specific locations. Unfortunately, you can't change the start date of industry in-game without editing the exe file.
