Infrastructure. 2 Domains Windows 2003 (DomainA, DomainB) each one their own DNS, IP addressing, etc. . All servers connected via 2 cores HP. I have a problem. Each x time, since the domainB i lose communication with a server of DomainA, but since the two cores are accessed without problems. When there is this cut is not loses communication at any time since the DomainA. Thanks.

Hi, Thanks for your post. Is this issue occurs on one server of Domain A or lose communication between Domain A and Domain B? What is the server OS version? Is the server has more than one NIC installed? You may post unedited ipconfig /all of both domain A and domain B servers which have the communication issue. In addition, ensure the server is up to date. Also, apply the latest update for the NIC driver. You may refer to the following KB article to troubleshoot this issue.

Hi thank you for responding. * Is this issue occurs on one server of Domain A or lose communication between Domain A and Domain B? Only is lost (random) with 3 servers that coincidentally have teaming * What is the server OS version? Windows 2003 Server SP2 * Is the server has more than one NIC installed? Has 2 NIC teaming Windows * ipconfig /all ServerA: IP: 172.23.2.20 MASK 255.255.0.0 GW: 172.23.2.1 DNS: 172.23.2.4/172.23.2.5 ServerB: IP: 192.0.40.10 MASK 255.255.0.0 GW: 192.0.40.1 DNS: 192.0.40.7/192.0.40.8 Both servers have updated drivers on the NIC and Windows. As I mentioned, communication is lost, deriving from PING, for example i lose 40 of 100 , but is ramdom and from any computer in the domainb Or you can call us within help, when I restart the server of teaming, usually it does not happen until past 1 week, weird not? Thanks
