After some testing I was able to recreate the problem constantly. When I loose connection and attempt to reconnect instantly; I get a new session. If I click on cancel on the reconnect window, wait one minute, then try to connect I get my Disconnected session. I checked the servers and I do have these registry entries; I might have to decrease the counter slightly, but I don't want to cause additional headaches. Could I, instead, increase the time it takes to get the reconnect pop-up window? Thanks everyone for your support!

Hi Miguel, It takes time for the server to detect a session has been disconnected, so if the client reconnects too quickly the server won't realise that there's an existing (nearly) disconnected session and will create a new one. The fact that things work okay %75 of the time means it's almost working okay. In an NT 4/MF 1.8 environment, you will have to enable ICAKeepalives by creating some registry values on each server. ICAKeepalive are enabled by creating the value: HKLM\SYSTEM\CurrentControlSet\Control\Citrix\IcaEnableKeepAlive, reg_dword, 0x1 and the KeepAlive timer is controlled by the value: HKLM\SYSTEM\CurrentControlSet\Control\Citrix\IcaKeepAliveInterval, reg_dword, 0x3C (60 decimal) This value is in seconds and 60 seconds is a good place to start. Much less and you risk disconnecting session every time there's a minor comms hiccup. The following policy could also be added to your machine policy template to make things easier: POLICY "ICA KeepAlives" KEYNAME "SYSTEM\CurrentControlSet\Control\Citrix" PART "IcaEnableKeepAlive" CHECKBOX VALUENAME "IcaEnableKeepAlive" DEFCHECKED END PART PART "IcaKeepAliveInterval (secs)" NUMERIC VALUENAME "IcaKeepAliveInterval" DEFAULT "60" MAX 600 MIN 1 END PART END POLICY ; ICA keepalives regards, Rick Ulrich Mack Volante Systems Ltd 18 Heussler Terrace, Milton 4064 Queensland Australia.

Hi All, I am trying to figure out what could be the reason why some sessions will not reconnect but instead just create a new session on another server. I have 20 servers (MF1.8, NT4) and they are in 5 different subnets; they all provide the same published application which is load balanced across all 20 servers. Our wireless users are having problems when they loose connection (walk in an elevator for example) when they try to reconnect they just get a new session instead. I do know: It does not happen always, I'd say 75% of the time the reconnect as they should. When it happens, they always connect to a different server and the server they were previously on has a disc session listed. Thank you for any insight.
