ADB error: cannot connect to daemon

Issue

I need help to get ADB working on my PC (win7 64bit) with the Samsung Galaxy S2.

I have installed the drivers coming along Kies, I think under sub folder "25_escape". The drivers appear correctly as "Samsung ADB interface" under the device manager.

When I run "adb devices" I get the following logs

>adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
** daemon still not runningerror: cannot connect to daemon

I'm wondering if it is a driver issue, or something else. I have several other android phones that are working just fine (HTC, Motorola, Samsung Galaxy S1 even works) but that issue is happening on the Galaxy S2 (and Tab 10.1 as well). I disabled windows firewall, and it is still stuck. I made sure Eclipse is not running and I tried to kill ADB from the task manager, but none of that helped.

Your help is really appreciated! Thanks!

Solution

Same issue for me. Was stumped. After I removed "Dell PC Suite" the problem went away.
