holographl Posted December 1, 2006 Share Posted December 1, 2006 We are running Filemaker 5.5 Server and recently have run into a problem. Filemaker was working fine then suddenly it starts with -20 Cummincation errors. Randomly Filemaker client will display a error window saying -20 Commincations error. We have replaced all the network hardware we can, moved Filemaker to a new server, and made sure none of the computers use Sleep mode. We use Filemaker 5.5 Client on Windows 2000 and XP machines. Server is 5.5 on Windows Server 2003. We have kind of run out of ideas if anyone has dealt with this or has an idea it would be appreciated.

Stuart Taylor Posted December 10, 2006 Share Posted December 10, 2006 (edited) Only time i ever had this other than via sleep mode was: 1. Disconnect client when idle was set in the file itself under certain user accounts. 2. The disc that filemaker server was installed from had a scratch in it... installed perfectly ...but one machine just kept getting kicked off for no reason. After server reinstall with new disc (disc image) it was fine. (ps knew to change disc as could not install updates 5.5v1>5.5v4 ... kept throwing up unknown error) Are you running 5.5v4?

Stuart Taylor Posted December 10, 2006 Share Posted December 10, 2006 Just an observation ... but you both seem to be running 2003 server. Has there been a service pack recently that could have caused this? For that matter is 5.5 supported on 2003 server? Stefan is your profile out of date as it says you using fmp 4?

holographl Posted December 11, 2006 Author Share Posted December 11, 2006 Microsoft did release a Security update a couple months back. This of course had a bug that they say did something similar to this. They then release a fix for the fix shortly after. We have installed the fix and it made no difference. Microsoft has also looked at our network and can not figure anything out, they say it's Filemaker. So you see we are getting hit with the blame game and not getting any useful information.

Steven H. Blackwell Posted December 11, 2006 Share Posted December 11, 2006 For that matter is 5.5 supported on 2003 server? No. But a number of people run it on that OS. Supported is maybe the wrong term. It is not certified agaisnt that OS by FMI. Steven Link to comment Share on other sites More sharing options...
holographl Posted December 12, 2006 Author Share Posted December 12, 2006 We have been running Filemaker 5.5 Server on Windows 2003 for at least 2 years now with no problem. This problem just started about 2 months ago. One interesting idea I heard about from a user in China is that he found that one network card on one desktop client was bogging down the system so bad that it screwed up the entire network. It seems the card starts sending out lots and lots of data even when it shouldn't be. This hogs all the bandwidth of the network and Filemaker can not maintain the connections to the other computers. We will be checking this out. I'll let you know. Link to comment Share on other sites More sharing options...
holographl Posted December 15, 2006 Author Share Posted December 15, 2006 We seem to have found the problem. It was a DLink wireless range expander. Somehow with it in the network Filemaker croaks. We have run it for a few days now without it on the network and Filemaker is fine. We don't know why this is happening but for now we're just happy to be running smoothly again.

Steven H. Blackwell Posted December 15, 2006 Share Posted December 15, 2006 You aren't trying to connect the server to the network wirelessly, are you? Steven Link to comment Share on other sites More sharing options...
holographl Posted December 18, 2006 Author Share Posted December 18, 2006 No. The wireless system is on the network but all servers are hard wired in to the network. Link to comment Share on other sites More sharing options...
