RE: [ActiveDir] OT:Exchange 2003 TCP 18053

[Coleman, Hunter]

Sounds like this is the port that Exchange has chosen for RPC traffic with the Outlook clients. Unless you make a registry change on the server, Exchange will pick ports above 1024 (more or less randomly) for RPC with clients. http://support.microsoft.com/kb/155831 has a passing mention of this.   Hunter From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Pelle, Joe Sent: Monday, February 14, 2005 8:52 AM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] OT:Exchange 2003 TCP 18053 Tony,   Thanks for the quick response!  It doesn’t appear that we have a static port assigned though.   Joe Pelle Senior Infrastructure Architect Information Technology Valassis / IT 19975 Victor Parkway Livonia, MI 48152 Tel 734.591.7324  Fax 734.632.6151 [EMAIL PROTECTED] http://www.valassis.com/   This message may have included proprietary or protected information.  This message and the information contained herein are not to be further communicated without my express written consent.   From: Tony Murray [mailto:[EMAIL PROTECTED] Sent: Monday, February 14, 2005 10:36 AM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] OT:Exchange 2003 TCP 18053   Could be that you have a statically mapped port assignment for a particular service (NSPI Proxy, IS, SRS, etc.).  Check out the following article.  You can the look for the corresponding registry entries.   http://support.microsoft.com/kb/270836   Tony   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Pelle, Joe Sent: 14 February 2005 16:28 To: ActiveDir@mail.activedir.org Subject: [ActiveDir] OT:Exchange 2003 TCP 18053   Hello!   When I do a netstat –an on my Exchange 2003 server I see a lot of connections on TCP 18053.  All of our email clients connect to this Exchange server and just about all of them appear to have a connection via this port.  No one seems to have any idea what that traffic could be…   Does anyone have any ideas?  Any help or insight is greatly appreciated!   Joe Pelle Senior Infrastructure Architect Information Technology Valassis / IT 19975 Victor Parkway Livonia, MI 48152 Tel 734.591.7324  Fax 734.632.6151 [EMAIL PROTECTED] http://www.valassis.com/   This message may have included proprietary or protected information.  This message and the information contained herein are not to be further communicated without my express written consent.
