Re: [Samba] Domain login delays w2k8 R2
Not much. I attached a screendump from Wireshark. This capture is made on the w2k8 machine. The traffic shown is sent to/from the ethernet address of the w2k8 machine. Remote Desktop traffic is excluded (the machine is used as a terminal server).

We had the same problem - 2 ~30 second delays while loading the roaming profile The solution at our site was not related to samba ... it was the McAffee enterprise virus scanner. By patching it to the latest version this 2 delays were gone. - do you use McAffee or a similar enterprise scanner? regards Maritn -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba

To explain that further: That was solved by mcafee Patch 7 for McAfee Enterprise 8.5 7. ISSUE: Changes made in Microsoft Vista SP1 and later, in how the operating system opens/views network files, caused delays in opening new network paths, with the On-Access Scanner’s Network Scanning feature enabled. RESOLUTION: The link driver has been modified to use a different method of accessing the network resources that avoids the delays imposed by the operating system change. Altough we use mainly XP we think that such a thing caused the delays - we discovered it by simply removing the virus scanner and tried to login with a roaming profile again -maybe try that too regards martin -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba

Hi! Valid point but I have not yet installed any anti virus software on this machine. I have also tried disabeling the firewall but it makes no difference.
