Dan, Here is our setup and it's working fine: Servers: 2 x Dell PowerEdge 2650 w/ 2GB RAM (active/passive cluster setup) OS: Windows 2003 Enterprise and Exchange 2003 Enterprise (latest patches/updates) One port on the Dual NIC is deactivated and one port is for cluster communication. Using a third Intel Pro 10/100/1000 for traffic. As far as your question..NO. First start would be to get the latest patches, etc for Windows software and Dell servers. Could it be that the recipient's email system is not working correctly? Thanks, Shawn. -----Original Message----- From: Dan Crain [mailto:DanC@xxxxxxxxxxxx] Sent: Wednesday, August 25, 2004 10:09 AM To: [ExchangeList] Subject: [exchangelist] Exchange 2003 on Dell Server http://www.MSExchange.org/ Has anyone had problems with there Exchange boxes on Dell servers? I can receive fine but some mail won't go out. They just sit in the que. A friend of mine had this to say.... "It appears that the servers that you cannot send to are timing out. They start to talk to you then timeout. I see a lot of discussions on this ranging anywhere from the NIC's on the Dell to both sides being Exchange 2003." Has anyone heard this before? Please let me know...
