Eric Ouellet's questions

I hope I'm at the right place (right stack exchange website). If not please tell me the right one.

I got new rights on a folder on a Windows server by being added to Active Directory Group for which I didn't had access.

But although I had rights, I was not able to access the folder. I had to logout/login in order for me to have access.

Why so? If it is the server that authorize me according to who I am, then why rebooting my machine (or logoff/login) is required to have access to that folder?

What is the minimum action to do to have access to that folder? Do we absolutely have to logoff/login ?

The same C# executable programmed to run on every nodes have those different behavior:

• HP: Run on one node only (one processorGroup) (any one of the 2). Problem: it suppose to run on every nodes.
• IBM: Run on all nodes (every processorGroup)

Both machine run windows Server 2012 R2 and have more than 2 cpus.

HP - 2x Intel(R) Xeon(R) CPU E5-2697 v3 @ 2.60GHz, 2597 Mhz, 14 Core(s), 28 Logical Processor(s) IBM - 4x Intel(R) Xeon(R) CPU E7- 4870 @ 2.40GHz, 2395 Mhz, 10 Core(s), 20 Logical

I try to answer my own question at stackoverflow. All details could be taken at this link.

To my opinion, it seems to point to a faulty driver on HP server or a configuration in the bios or windows.

Any idea what could cause that exactly ?
