common firewall driver network issue

Hi,

 

On some PC we have issue that it drops connection to differents apps  ex.SAP,EXCHANGE,FILE share

Ping looks ok all the time,switches ok.

it´s look that it is something higher in the OSI-modell

The following from the  trencw_log

 

Example:

2009/08/28 07:43:06.145 00000db0:00001758 [I] Drop: 1.1.1.1 -> 2.2.2.2 (6) sport=1123, dport=445 (reason="Unknown TCP packet").

Re: common firewall driver network issue

Hi,

 

We will need more information like registry and firewall policy dump to find the root cause.

 

You can first try OSCE 10 SP1 which is available here (scroll down to Service Packs section)

http://www.trendmicro.com/download/product.asp?productid=5

 

If the issue persists after SP1 deployment, please use latest CDT tool  to collect debug log  (http://www.trendmicro.com/download/product.asp?productid=25 ) and submit a support case to Trend.

 

Thanks.

Re: common firewall driver network issue

Ok we have tried the 10 SP1 update but still the same problem :smileysad:

 

The problem is that, when we run the cdt tool the "tmlisten.exe"  process shutdown i think.

The problem never happens when we running the cdt tool

But i try to do a new cdt log file now after the update grrrrr.
