HI, im having issues with swarm not connecting properly. i can see all agents in the co-coordinator but mostly they wont start when i hit build. or if they do start then they fail almost immediate and disconnect. i can ping the co-coordinator from each agent but when i ping from the co-coordinator i get thew bellow. any help would be much appreciated 5:02:31 PM: MEL-7-LYNX04A (User = RENDER-MEL, IP = 192.9.200.115, Version = 1.7.2892.0) is currently Available, Unassigned 5:02:31 PM: MEL-7-LYNX04A: IP address for this Agent cannot be verified - Coordinator and local mismatch or DNS inactive! 5:02:31 PM: MEL-7-LYNX05A (User = RENDER-MEL, IP = 192.9.200.96, Version = 1.7.2892.0) is currently Available, Unassigned 5:02:31 PM: MEL-7-LYNX05A: IP address for this Agent cannot be verified - Coordinator and local mismatch or DNS inactive! 5:02:31 PM: MEL-7-LYNX06A (User = RENDER-MEL, IP = 192.9.200.33, Version = 1.7.2892.0) is currently Available, Unassigned 5:02:31 PM: MEL-7-LYNX06A: IP address for this Agent cannot be verified - Coordinator and local mismatch or DNS inactive! 5:02:31 PM: MEL-7-NODE01 (User = RENDER-MEL, IP = 192.9.200.131, Version = 1.7.2892.0) is currently Available, Unassigned 5:02:31 PM: MEL-7-NODE01: IP address for this Agent cannot be verified - Coordinator and local mismatch or DNS inactive! 5:02:31 PM: MEL-7-NODE02 (User = RENDER-MEL, IP = 192.9.200.123, Version = 1.7.2892.0) is currently Available, Unassigned 5:02:31 PM: MEL-7-NODE03 (User = RENDER-MEL, IP = 192.9.200.127, Version = 1.7.2892.0) is currently Available, Unassigned 5:02:31 PM: MEL-7-SATURN18 (User = DAC, IP = 127.0.0.1, Version = 1.7.2892.0) is currently Busy, Unassigned 5:02:31 PM: MEL-7-SATURN18: IP address for this Agent cannot be verified - Coordinator and local mismatch or DNS inactive! 5:02:31 PM: MEL-RENDER-02 (User = RENDER-MEL, IP = 192.9.200.122, Version = 1.7.2892.0) is currently Available, Unassigned 5:02:31 PM: MEL-RENDER-02: IP address for this Agent cannot be verified - Coordinator and local mismatch or DNS inactive! 5:02:31 PM: [Network] Remote Agent ping complete ---

We had that issue too and it turned out it was a problem with Windows not allowing Swarm Agent to create the **Jobs** folder inside the **\DotNET\SwarmCache**. So, we manually created the folder and that fixed it. Looking at the date this question was posted I’m guessing you already worked it out but I thought to write it down in case someone else comes across the same problem. ---

I know this post is really old but I wanted to thank you for sharing the issue with that stupid “Jobs”-Folder inside of SwarmCache. I manually created it on my coordinators computer and it worked after hours of searching for a solution!
