Hello All, We are having an problem with attachments since this morning, the systemconfiguration: Windows 2000 Advanced Server SP2 Exchange 2000 server SP2 Clients: outlook 2000 SR1 the problem is that all emails with attachments for outside our domain, (rotterdam.nl) can't been opened within outlook 2000. This is for all type of attachments, we use groupshield on the exchange server, en mcafee on the clients, but even with groupshield en mcafee disabled the problem exists. When we open the same email within outlook express, we can see the attachment en open it with no problems, also when we sent an email with attachment to one of oure unix servers from outside domains, we can open the attachments with no problem. It looks like it only happends outlook 2000, all other mails, have no problems at all, and sending atachements from internal to internal and internal to external works also fine. We get also some eventlogs on the exchange server the same time we try to open an attachment in outlook, Type: Failure source: MSExchangeIS Category: Content Engine event-ID: 12002 Date: 18-12-2002 Time: 16:41:31 User: n.v.t.

For more information, click <http://www.microsoft.com/contentredirect.asp> http://www.microsoft.com/contentredirect.asp. I looked on technet, eventid and google, it looks to me quite vage problem, there were no modifications on the server, the only thing we did this morning was adjusting the diagnostics loggin setting of the exchange server smtp from none to minimum, i think it's somehow related to this action. If you have an idea about this, let me know Thanks, Martijn Spelt Computer & Network Services Gemeentelijk Havenbedrijf Rotterdam Tel 010- 252 19 76 Fax 010- 252 19 57 E-mail m.spelt@xxxxxxxxxxxxxxxxx Internet www.portofrotterdam.com World Port Center Wilhelminakade 909 3072 AP Rotterdam Nederland
