When a user log onto domain, where can I find which DC authenticated through kerberos in DC event log?
I see only the user IP, workstation hostname, user name, but no DC information?
from client, I can issue %logonserver% or nltest /dsgetdc:sea. But I need to get a report what DC authenticated who. How can I update this information?

Also, if the user is home office user through VPN, it doesn't seem the logon event is even being recorded in DC's security event log.
For VPN users, how can I trace which DC authenticate which user?

DC: Windows Server 2012

In SBS 2008 (and 2011) the maximum number of concurrent VPN users is set at 5 out of the box. You have to make a change in the Routing and Remote Access console to increase the number allowed.

Not sure if a similar limitation exists in Server 2016 Standard with Essentials Role. With bad weather today in NJ I have most clients working from home. One has 21 users Logged into VPN. No issues, but I'm just trying to find out if there is any limitation on the number of concurrent VPN connections in 2016 (and how it can be increased) - just in case...

Anyone know?

I recently installed a Cisco 1921 router as the def gateway for my network. I also have a Cisco ASA5505 9.2 on the LAN behind the router. My goal is to allow AnyConnect Client SSL, Clientless SSL and site to site VPN passthrough on the router. So far I had a chance to test Client SSL and Clientless SSL and my router configuration does not seem to be working. From the LAN I can establish a VPN session to the outside interface of the ASA. Can you please review my configuration and point me in the right direction?

I have a client that we support that just purchased a 10 person office across town and need them to connect to our office.  The 10 users will be connecting to our applications via remote desktop services (RDS server 2012 R2) at the main office.  I am looking for a router / firewall appliance that offers both site to site VPN and Client to site VPN.  My goal is to use a robust solution that offers support that I can easily setup and understand.  Some have recommended Sonicwall and Watchhguard, but their business strategy requires that I go through one of their partners - who may be in direct competition with what we do - provide IT support.  We simply want a solution that is under $1000 per appliance, easy to setup and logical and someone to help should we have questions.  We gave also looked at Barracuda networks as well.  But with any of these appliances, I need specific models to go with.

We will need the VPN for both the branch office we are connecting to as well as allow users from our current office to connect remotely from their homes.  So total # of VPN users could be 20 users.  Any guidance would be appreciated.
Don't get me wrong, I have 20 years IT experience and can configure most routers easily and have used Most in the past.  Just don't know the current offerings with subscription based / more robust VPN solutions.

Hello Experts,
I have a strange issue I am hoping someone can help with.  We have set-up a VPN tunnel to another organizations servers in AWS, all connectivity seems to be fine back and forth.  What we cannot do is RDP to the servers in AWS, before you throw up firewall let me explain the oddities of the issue.

The consultants of the organization can come to our office and, from our network, RDP back to these machines without issue.

We thought it was a username?password issue but they tested our credentials from their machines and they were successful.

We have disabled firewalls yet still unable to connect.

We found out that from our network we can take a fresh PC, never joined to our domain and connect via RDP.  Once that machine is joined to the domain the connection can no longer be made.  Here is the real kicker, removing the machine from the domain, does not change the issue.  Instead it still suffers the same inability to connect via RDP as the domain joined machines.

The best I can come up with is our GPO is making some registry changes that are not being reversed once dis-joined from the domain.  

Does anyone have any idea of a setting that could cause this issue?  I have cleared the DNS suffix, tried static and DHCP, Admin logins, Firewalls disabled, tracert looks good (issues there would be present regardless of domain memberships).  I am at a loss, help would be greatly appreciated.

Thanks,
Mark

The Sonicwall OS is 5.x. This is just the base router, no extra licenses for IPS, malware etc... I recently setup L2TP VPN for a couple users - using long and complex Pre-shared secret and each have a very long and complex password... I have been blocking obvious attempts from just IP addresses trying to access a webcam port using the info I found on how to do that - but blocking an IP address from WAN  - doesn't seem to affect efforts of a couple outsiders trying to access via L2TP - I see the failed messages from the different stages... but they keep trying - and added their IPs to my 'Blocked IPs' address object group has no effect.
I want to be able to deny them access to even try to authenticate and get them out of the logs - like blocking IP addresses.
Anyone savvy on the SonicWALL as to how to prevent attempted L2TP connections from undesired sources? Is there a way to create access rules to block from L2TP to ANY or LAN, we have the network on the X0 interface.
My understanding is there is a VPN access list on the SonicWALL - but it does not apply to L2TP.
Thank you!

Intro

I would like to setup my personal firewall directly to the Netgear DM200 ADSL Modem (in modem mode).

This would allow me to connect directly through VPN to my work ASA5510.

Setup

ADSL Phone line <-> ADSL filter/splitter <-> Netgear DM200 <-> ASA5505 <->BT HomeHub5

I have set the DM200 in modem mode with the username "bthomehub@btbroadband.com", i dont know the password or the Authentication method "PAP or CHAP or MSCHAP"

The ASA is also asking for an VPDN group which I have no details for....

The DM200 is working because I can access th einternet when connected to the LAN port when in Modem mode.

Issue

Ultimately i just want to securely VPN into my work ASA but it would be useful to implement the Firewall for all outgoing internet traffic instead of placing it behind the BT Homehub5 that im replacing .

I would really appreciate it if anybody could offer any advice or help.

I have several Dell SonicWALL's in service but with one of them,  a TZ205 wireless-N, I can't remotely manage the Sonicwall.  I can connect to all computers at this remote location from a VPN tunnel, Site to Site.  If I connect to a PC behind that SonicWall I can then connect and manage the SonicWall.  This is an extra step that I don't want to have to deal with.

I've compared settings to my other SonicWalls's but none are the exact same model.  As far as I can tell everything is the same.

What am I missing?

Hi,
I have a user who cannot login to our VPN using the in-built MAC VPN in System Preferences. The error implies the username/password is wrong. The logs on the Windows VPN server say the username/password are wrong when the user tries to login from the MAC.

The SAME username and password works fine when using the in-built Windows 7 VPN.

So the problem must be the MAC, right?

My username and password work fine on the MAC's in-built VPN and the Windows 7 in-built VPN.

I have a child domain in a 2012 R2 Forest that has an outdated name.  The forest has Exchange 2016/2010 in production but this particular child domain does NOT use Exchange in any capacity.  It is only for hosting VPN clients to forest resources.
There are several articles for renaming a domain but many mention the rename is not supported if any Exchange other than 2003 is deployed.
Is a domain rename possible in the situation?

Cyber Threats to Small Businesses (Part 1)
Cyber Threats to Small Businesses (Part 1)

This past May, Webroot surveyed more than 600 IT decision-makers at medium-sized companies to see how these small businesses perceived new threats facing their organizations.  Read what Webroot CISO, Gary Hayslip, has to say about the survey in part 1 of this 2-part blog series.

I'm trying to figure out the best course of action in order to setup office laptops on Server 2012 R2 Standard while keeping desktop configs the same in the office as well as home.

With previous server versions when I've done this I would locally joined the laptops to the domain and configured it as a local workstation then, working from home just meant connecting via VPN and basically work the same from home as in the office.  I haven't done this yet on Server 2012 so I thought I'd ask in case there were more efficient ways of going about this.  BTW, I didnt think RDP would be applicable here because RDP'ing into the server when locally in the office seems necessary.

Thanks everyone

Hi All,

My company Scenario:

I have connected the branch office to main office using VPN.

Main office is running under domain environment and using a Watch guard as a firewall.
Branch office is running in a work group environment and using a Billion VPN Wi Fi router.

VPN has been set up between Watchguard Firewall (XTM26) and Billion Wifi Router (Bi Pac 8920nz)

VPN is working fine. I am able to take remote of all the computers located in to the branch office using "Microsoft Remote Desktop" from the main office.  

Problem:

I am not able to ping any of the branch office computers. I can ping branch office wifi router and network printer only. What could be the reason?
