We have couple of instances launched on Amazon cloud. I am able to access drive and shared folders on all servers except one.

OS is windows 2008 R2 64-bit server. What might be the reason and how do it fix it.

Interesting problem.

Whilst no expert on Amazon Cloud, I did recently help set up an environment, albeit not Windows 2008 R2. I am not sure if there is a fundamental problem with 2008 R2 64bit.

First up what makes this server different from the others ? Are you getting error messages ? Have you checked the logs ? Any of that additional information might help identify the root cause.

I do know that 2008 R2 with access-based enumeration does make security / permissions in Win Server more *interesting* and easy to confuse. Interesting how the more advanced we get, the improved sophistication seems to translate into increased complexity (*sigh*).

Have you read through the security center : http://aws.amazon.com/security/

Have you double checked permissions for 2008 R2 shared folders :  http://technet.microsoft.com/en-us/library/cc726004.aspx  (note the special link for access based enumeration)

Have you filed a support ticket (or have premium support - which I have recommended to the site I was assisting) with Amazon ? : https://aws.amazon.com/support

Then what about the basic environment like firewalls and such like ?

Anyway, if you can provide some more information, it should (?) make it easier for experts to help you.

Hi mark_wills

Error is : " Windows cannot access \\path"
              Check the spelling of the name. Otherwise there might be problem with your netowrk.
Server Firewall is disabled
Allowed port no 445 to access shared folders on cloud.
No error found in system logs.
Do not have subscription to premium support as these servers are launched on hourly basis for testing purpose.

Hi anuboggaram,

Apologies for the laggard response time, but didnt see the alert that you had already posted (no excuses).

Well certainly sounds like a permissions error, or possibly a mapping error.

Have you double checked File and Printer Sharing (needs to be on) ? It can sometimes be overlooked, and double check the port exceptions in the firewall - I have seen firewalls dynamically drop exceptions.

If you are doing this kind of dynamically and continuing to do so, then support might not be such a bad idea, but up to you. There are a few support choices, did you look into any of those other avenues ?

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

Found a couple of potentially interesting links from the amazon support area

1) talks about sharing folders, worth scrolling down toward the end https://forums.aws.amazon.com/thread.jspa?messageID=174539&#174539
2) similar advice provided : https://forums.aws.amazon.com/thread.jspa?messageID=113886&#113886

And what is different from you other servers where it is not a problem ? Suppose that is where I would start - checking and comparing various settings... Gotta be something slightly different causing the problems.

Anyway, please let us know how you are going, and if you can find the answer, please post here.
