- Network model of e as follows: Client -> Server -> ISA - Server's e-job DC, DNS, DHCP and File Server. Configurations quite strong (this is a dedicated server to HP) and use RAID 5 for the HDD. Network infrastructure will reach speeds of 1GB (network cards and switches are supported) - The client machine has the Domain Join and map network drive on normal runs but only condition is to create a new folder on the network drive very slowly, about 1 minute to create more complete, during which time the machine hangs always. Then test by e at this client machine, e not to join another domain (ie the machine is removed from the Domain, to run the Workgroup), then map network drives from the server to create new the normal folder, no delays and no computer crashes. - Moreover, the machine has the Join Domain, open Excel files on the network drive is also very slow to save. Also lost more than a minute to complete files. - E also tried reinstalling the new OS, and the new configuration also remains. - In this model, the ISA where anything related to the internal network, did not He? E found on ISA at it because the error message as follows: ISA Server Disconnected a non-TCP connection from 172.16.1.253 Because the IP address for this connection limit exceeded Was.

Hi lexus2012 , Thanks for posting here. After reading your post I understand that you have encountered slow performance when you access a shared folder. Before we move on, I would like to confirm the following information with you: 1. What OS version of your client and server? 2. What group policy setting you had deployed to client ? 3. Have you deployed Anti-Virus software on your server ? 4. Please post any related event log on both server and client when this issue encountered . 5. The ipconfg /all result and rout table of both server and client will be helpful. You may like to check if it worked with following the steps : 1. Please make client computer direct connect to server and verify if it still. 2. Disable any anti-virus software on your server. 3. Dis link all group policy which applied to client computer and user account. 4. Template disable the NIC which connect to ISA server on your server and try access again. It’s a not good idea to install AD on a multi-NIC machine. Active Directory communication fails on multihomed domain controllers http://support.microsoft.com/kb/272294/en-us And for the ISA issue it is recommend you to get further support in the Internet Access forum so that you can get the most qualified pool of respondents.
