NI-DAQmx long boot time

[PhysicsGuy]

I recently upgraded to a new version of the NI-DAQmx drivers (9.6.1 and then 9.7.0) from a much earlier version (9.4.0).  After the upgrade, the computer hangs on the "Please Wait" screen as it is starting windows for about 20 minutes.  This is before I can entry the user name and password.  Removing all the NI software on the machine fixes the problem.  I am running windows 7-64 bit and am joined to a network.

Any ideas?

Same thing here. Seems updating the MAX from 5.1 to either 5.3.1, 5.3.3, 5.4 causes this problem.

We have this on 4 Lenovo laptops and a Panasonic laptop.

But: This only occurs when the computer is not connected to LAN or connected via WLAN. When a network cable is connected boot times are normal.

Are there any firewalls or antivirus software on your computer that could be causing problems?  Also, did anything else change on your computer other than upgrading DAQmx?

[PhysicsGuy]

No changes to the rest of the computer.  I did find the solution that the LABView guys are using and it worked for me as well:

    - Disable the NI mDNS Responder Service through services.msc
    - Modify the following registry key (Change Enabled to 0)
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WinSock2\Parameters\NameSpace_Catalog5\Catalog_Entries\000000000005
    - Note: Do not just pick 000000000005, click on each catalog entry until you find the one whose
        DisplayString is mdnsNSP and set that one's Enabled to 0.
        For 64-bit Windows, you may have an additional key under Catalog_Entries64 which should also be set to 0.

I agree with PhysicsGuy.

Had the problem on 3 computer. Updated DAQmx from 9.5.2 to 9.6.2 and boot up time was around 15 minutes.

After following the instructions from PhysicsGuy everything is fine and windows 7 x64 boot time is normal.
