Hi,

Why is it bad to have 2 physical NICs on 1 server with 2 different IPs but on the same subnet?

ie.

nic 1: 192.168.1.1
nic 2: 192.168.1.171

This is a Hyper V server 2012 R2  so nic2 is used for the virtual switch and all the VMs are connected to it.  Nic1 is what I use to RDP into.

Why is this bad? will it cause issues or just not "best practices" ?

Thanks,

We have a Windows Server 2008 R2 Domain Controllers, other Server 2008 Servers, a Server 2003 Server, and Windows 7 and Windows XP clients.  Can the network be setup so that computers can't access it unless the computer meets specified criteria?  For example, we don't want a computer to connect unless it has McAfee anti-virus, is managed by McAfee Orchestrator, and has a DAT file not older than a few days ago.

Use the windows 7 pro backup , when restoring it , attention on the time stamp of backed up is not matched the time really done ?  Time zone is -8 which shall be +8 zone right ?

How this is made  ?

People,

I've got the existing Exchange Server 2013 Standard SP1 that is running as MBX&CAS role in one AD site called Default-First-Site-Name.
I want to decommission it so that I can run the both MBX & CAS on new Win2012 R2 VM so I can configure DAG on the other AD site called Head-Office1.

Existing:
AD Site Default-First-Site-Name
PRODMAIL14-VM [Mailbox & Client Access Server] - Windows Server 2008 R2 existing legacy.
PRODMAIL15-VM [Mailbox server only] - Windows Server 2012 R2 newly built for DAG.

AD Site Head-Office1
PRODMAIL20-VM [Mailbox & Client Access Server] - Windows Server 2012 R2 existing newly built for DAG.

Proposed:
AD Site Default-First-Site-Name
PRODMAIL14-VM [Decommissioned]
PRODMAIL15-VM [Mailbox & Client Access Server] - Windows Server 2012 R2 setup for DAG with Head Office.

AD Site Head-Office1
PRODMAIL20-VM [Mailbox & Client Access Server] - Windows Server 2012 R2 existing newly built for DAG with PRODMAIL15-VM.

How to do that safely without causing email flow issue during the production business hours ?
What're the steps in installing CAS so that it does not cause any email flow during the business hours on PRODMAIL15-VM ?
If I install the windows update now during the business hours on PRODMAIL15-VM is there any impact or problem when I reboot it ?

Thanks, in advance.

Hello I am working on enabling QoS policies on my VDI Desktops. I created the GPO settings below in the computer policy. I see the GPO applied successfully. When I run an RSOP report I see the workstation reporting that the policy is applied. When I run wireshark, I am looking at the DSCP values and they are 0. Am I missing something that I didn't enable? I'm looking to enable QoS on outbound SIP and PCoIP traffic but neither are being tagged with the policy settings I put in.

Honored Experts.

Im new to Microsoft Online and OneDrive Business.
I have set up an agreement for a very small company.
I have uploaded a folder called SHARED to OneDrive and shared this for all users.
However NONE of the OTHER users are actually able to see this folder in Windows Explorer OneDrive.
They have to go online and see shared folders to access it.
How do I make this shared folder visible in Windows?? :-)

I have a characteristic in my domain that has never caused an issue, but is now troubling a group installing a new software program in my environment.  We have a domain with two 2008 R2 AD machines.  I always join all the computers and servers to the domain, and require users to use an AD login.  The issue - when I login on any computer with domain\username, it "looks like" WORKGROUP\username.  In fact, I can use either to login.  When I write code in VB.NET and get the identity a users, it always says WORKGROUP\username not domain\username.  My software company is saying that my users are not really authenticated users, and that is why we are having some issues accessing certain resources.  Not sure if I really have a problem, or where to begin to look/

last year a windows server 2012 Essential was installed  and manually workstations disjoin the old domain and join windows server 2012 Domain in a small office environment, I could not use the server connector wizard at that time so I manually joint the new domain.
Now I have to use  server connector http:\\fs1\connector to be able to manage these windows 7 from dashboard and run backup. However when I run it, I get to the "Type User Name and Password) as in attached fig. and keyboard type name as you see in the picture. I do not want to dis join from the domain. All I want is to be able to backup from the server (Using Azure Backup)

Thank you

I'm seeing a behavior on Win2012R2 that's different from Win2003R2, on how routing works on multi-homed servers that don't have routing turned on. I want the Win2012R2 server to behave like Win2003R2.

Win2012R2 server
NIC1_Production
172.18.138.60
255.255.255.0
GW 172.18.138.254

NIC2_Private
172.20.0.1
255.255.0.0
no GW

I have 172.16.0.0/24 devices on my NIC2_Private network. But on the production side of my network (on the NIC1_Production side), several router hops away across my MPLS I also have 172.16.0.0/24 devices. I want this 2012R2 server to only talk to the private 172.20.0.0/16 network, which is why I multi-homed a server without routing turned on.

The problem: On the 2012R2 server, when I ping devices in the 172.20.0.0/16 range that exist on my production network (but not on my private network), the pings try NIC2_Private for the first attempt, but then go out NIC1_Production's gateway (my production network) for the rest. Why, if the 172.20.0.0 is a network directly connected to the server? In contrast, on a Win2003R2 server, the pings only stay on NIC2_Private and don't go out NIC1_Production. How do I change this 2012R2 behavior so it acts like Win2003R2?

I have a Win2003R2 multi-homed server connected to both networks also, and it doesn't pass the private traffic to the production network (which is what I want).

As of now, I don't have any devices on both networks with the same IP address. That may change at some point in the future, …

Hi Experts,

I have about 20 (two of each redundant wan links) running off of two switches 10.x.4.3 and 10.x.4.4. I have windows static routes to connect to the following wan link using 10.x.4.3 only at the moment. I am a bit reluctant to add the redundant route pointing 10.x.4.4 to the same destination so it could failover the to the redundant link in case of the link failure on 10.x.4.3.

I can put in an additional static pointing the same ip to 10.x.4.4 with metric of 35 but I needed to make sure that windows will only use the 2nd link when the primary link goes down.

Or I can do this on the cisco asa firewall pointing both links with a metric of 1 and 2. Just trying to find the best and safest approach.

Any help with be appreciated, Experts,

Thank you

Two desktops, one laptop, all running the latest Win 10, all on the same workgroup.  File/printer sharing enabled.  All machines discoverable.

About three weeks ago, they stopped talking to one another.  I can see the computer names in my network list.  I can open a cmd box and ping another computer successfully.  But if I try to map a drive or open one of the other computers, it says WINDOWS CANNOT ACCESS \\FRONTDESK (or any of the other computer names).

Running network diagnostics is useless.  It basically comes up and says yeah, you can't connect, buh-bye.

I'm at my wit's end.  I have been researching this for weeks.  I've tried everything that I see suggested and I still can't use my network.  For example:

I've changed the workgroup name to something different and back.
I've renamed the computer
I've turned off anti-virus
I've turned off the firewall
I've tried to force my computer to be the master browser


Has anyone had this problem and if so, what did you do to fix it?  Thanks in advance!

Brief overview: last 4 months, I've migrated to a new Windows 10 laptop.  I'm a consultant, so I bounce across multiple customer domains.

Customer A is a large corporation that I can physically connect to their network.  They run a full AD network setup, but I am NOT a member of the domain.  I have assorted network drives mapped to shares I need for work.  Example: The W drive is mapped to \\DevServer\Software.  This arrangement has worked for years.  If I need to access their network remotely, I use Global Protect as a VPN provider.  With this, everything still plays well.

Customer B is another large corporation.  I only access their network via another piece of VPN software - PulseSecure.  This allows me to VNC or remote desktop into assorted servers.   This has worked well for years.

Customer C is me.  I work from home at times, I don't run an active directory - typical home workgroup set up.  If I need to support Customer A or B, I just fire up one or both VPN services and off I go.  There has never been a conflict.

----------------------------------------------------
The issue:

Yesterday, I am at Customer A, connected to their network, no VPN software running.  Tried to go to my network drive - server not found.  Weird, I open up a command window and ping it:  "ping devserver"  The response is "Pinging devserver.customerb.com:"

It's picking up the wrong domain somehow.  Double checked - no VPN software running.  Verified in the network settings that my…

I am trying to determine why all the PCs on my network are not showing up when I click on my Network icon.  I can see all the PCs that on my local segment, but PCs that are at other building do not appear under my domain.  I know they're all list in AD and I have discovery and file and print sharing turn on for all PCs.  Could there be something misconfigured in DNS?

Thanks

Network Connectivity issue. I can ping the DC which is the SBS 2003 Server by Name and IP Address from all of my computers and servers within my network and also RDP into the Server, but I cannot access any resource from the DC for ex: (shared drives, mapped drives, network printer, etc.). DC also host Exchange server 2003, but cannot access exchange from workstation using Outlook. Pretty much cannot access anything on my DC, however; from the DC I can access everything on all of my computers on the network. So definitely there is a connectivity issue on the DC itself. Please advice.

I have 2 domains. Domain A and Domain B.
Domain A has 2 websites on single server.
Domain A is going away and the web sites will be moved to a server in Domain B.

Problem is, that web master does not have time to reconfigure all the domain information in the existing code & config files to reflect the new server names. The systems cannot go down for the time being. Will something like this work?

  • transfer the Domain A's DNS zone information over to Domain B - this way the A.com domain record still exists
  • Going into the newly transfer DNS records and change the IP of the 2 website to point their new IP's in the B domain

anyone typing Server1.A.com in a browser will get resolution from the DNS server in Domain B which will then return the IP of the new website in Domain B.

My ADFS Proxy server lost it's trust from our Federation service when we were having issues with our firewall.

Now when I go to reestablish that trust relation ship it fails.  We are using the same certificate and all that information in the first few screens when trying to reconfigure in the Web Application Proxy Configuration Wizard.  When we hit the Configure button we get an error:

AD FS proxy could not be configured.

An error occurred when attempting to establish a trust relationship with the federation service. Error: Unauthorized. Verify that the service account has administrative access on the target Federation Server.

The Event Viewer for AD FS shows an error ID of 393.

I am running Windows 2003 Server R2 as a domain controller. Has Buffalo Terrastation with 4 2-Terabyte hard disks configured as RAID-5. I mapped 3 shared folders and all workstations from domain group had access to the shared folders until I lost power to the TerraStation overnight. I restarted the TerraStation, was able to ping its ip address, was able to login from explore and saw all my shared folders. The RAID reports NORMAL but no worstation can access the shared folder anymore.
Error from Workstation: "An error occured while connecting to drive K:. The network name cannot be found . The connection has not been restored."
I rebooted both the server (domain controller) and the terrastation but still could not access the shared folders. I logged into the Terrastation and created another "test" shared folder. I mapped to the shared folder from the workstation and was able to read and write to the NEW shared folder but my other old shared folders are still diving the error.

Please HELP. Thanks in advance.

Does anyone know of a SQL query that can be run against the SCCM database to pull out the information that can be found on the "update" tab on the endpoint protection client on each device, namely I need the results to return device name, definitions created on, definitions last updated, virus definition version, spyware definition version.
