Hi all,

We have a router on 192.168.0.1 and our main server has 2 NIC's one has the IP address of 192.168.0.254 which is the main IP address but the other NIC's IP address is 192.168.0.3 as this is a target NIC for an iSCSI NAS drive.
We're geting issues logging onto the router as it keep timing out but i've noticed that when i try to ping the router on 192.168.0.1 i get a few "reply from 192.168.0.1: bytes=32 time<1ms TTL=255" (this is fine)  entries followed by "reply from 192.168.0.3: destination host unreachable" which i suspect is why the connection to the router is not working but i can't figure out why this is  ?
Anyone think why this is ?
Thanks

Hi,
We're rolling out Windows 10 Pro for our users and I'm having an issue with printer(s) re-installing after deleting the roaming profile. Profiles are stored on a windows server 2012 R2 file server and our laptop has windows 10 pro OS.

It's been our practice that when a user gets a corrupt profile we delete/renamed (old_profile.v6) the profile on the server and on the local client so when a user login to a client it will create a fresh profile on the server and locally in the client.

With Windows 7 Pro when I delete the profile (server and client) nothing is retain everything is fresh and with windows 10 Pro after I delete the profile (server and client) the printer installed on the user profile come back.

Is there a setting or something that I need to change in windows 10 pro so when I delete the user profile on the server and client nothing is retained and the profile created is a fresh copy?

Thanks in advance for the help.

We have a Synology NAS is our environment, and as of about a week ago we are no longer able to access it by its name -- only via its IP address.  The network is a Windows Server 2012 AD domain.  All the NAS functionality is still there, and nothing else on the network is behaving this way.  Nothing has changed on the NAS (other than the regular Synology DSM updates).  We have tried rebooting the NAS, as well as, the DNS server; removing the DNS entry for the NAS; adding a static DNS entry for the NAS -- none of which helped.

I just got a general question :
 
If there is a company with 2 Managed switches(Dlink) and all computers and servers are connected to the switches. And has a dlink router.
If a user complains, accessing files to the server is slow from my computer .
How do i troubleshoot? from where do i start? is there any specific tools/softwares to troubleshoot.
I AM just new in networking career. so sorry guys if its a simple question.

Hi everyone,

This issue did not exist last week, and nothing has changed on our network that I know of.  I'm the sole I.T. employee with access to make changes.

Here is our basic LAN:

*Internal Network -> Split into multiple subnets as shown below:

Primary Location: Main network -> AAA.AAA.118.0/24  (DNS servers located with Domain Controllers)
                                WiFi network -> AAA.AAA.119.0/24   (DNS server is provided by Virtual Linux server)

Remote location 1: Main Network -> BBB.BBB.0.0/24 (DNS servers located with Domain Controllers)

Remote location 2: Main Network -> BBB.BBB.1.0/24 (DNS servers located with Domain Controllers)

1. The primary location and both remote locations are communicating between each other just fine.  
2. Both remote locations can access the External company website just fine.  
3. The Wifi network at our Primary Location can access the external company website just fine.
4. No other issues with external websites at our Primary location, just issue accessing company website.

Company website is:  www.bhbinc.com

When accessed via our Primary locations's Main Subnet, we get this browser error:  "This site can't be reached.  The connection was reset"


Any suggestions as to where to look for the cause of this issue would be greatly appreciated!

We have a Windows Server 2008 with 3 Virtual Servers

We use Comcast and have about 30 PC's on the network with Netgear switches.

We got hit with a Backdoor Virus

We will be replacing Malware Bytes Premium  with their Anti-Exploit program.

Servers are virus free.

I have notice pinging the Servers within the office has slowed - Should always be a response of 1ms. I am getting timeouts and pining 8.8.8.8. comes back with 25-30ms replies, but occasionally times out - Even pinging the primary Servers 192.168.1.21, etc occasionally times out.

DO I have a bad switch? I notice lots of collisions on the switches - blinking constantly - Ethernet does that - not sure where to look. It is ok occasionally, but then everything slows down to a crawl. instead of pings from office computers getting 1ms responses it will come back as 1ms and then 20ms, and have timeout.

Not sure where to start looking. Waiting on anti-exploit program to replace Malwarebyte Premium which was not means for Servers.

Everything was fine earlier, but had to reboot because Routing and Remote Service could not be stopped. It hung on stopping. I had to reboot Primary Server. It is now slow with slow pings.

No Virus currently present but network is slow in both pings to the primary Servers and pinging the internet.

I need to find out why our network is so slow. Pinging a local server and having it time out sometimes is obviously a problem. Pinging 8.8.8.8 gets good replies sometimes but …

I'm trying to share files and folders between a Windows 10 and Windows 7 PC, but I'm having the following problems.  I'm not sure how to share permissions or what kind of network to select to do what I want (ie, Home, Work, Public):

*Computer A and Computer B want to be able to see one another's Public folders and shared subfolders under their User directory, but are able to see the entire user folder and all subfolders instead.

*Connecting from a Windows 7 PC to a Windows 10 PC says the user account "has been disabled;" is there a way to get it to prompt for a password instead?

*There is no domain, so should I connect using the full ComputerName\UserAccount?  Would having the same user account and password as the target computer help?

Thanks.

Hello EE,
We have a GPO that is to disable all windows firewall since we have a corporate solution.
My question is if I look all but the home/work networks are disabled, but I can't determine what is missing to get the home/work to also be disabled.  It is currently on for all Windows 7 clients.

I shut down 1 of our DC's to change the battery backup.  One of the member servers had the server I shut down as it's logon server.  I rebooted it and it did not get a new logon server.

Why would this happen?

How do I resolve it?

Hello Experts-

I am having some network issues starting a few days ago.  Initially I thought it was a DNS issue as the webpages would fail to load then immediately load once refreshed.  I noticed a few DNS log errors in the even viewer as well.  Upon checking the DNS server and NIC it seems to be ok.  An nslookup will sometimes point to the correct server and address sometimes and others it will time out.  Next I started looking at connectivity from the servers and the weird thing is we still have internet connectivity, albeit not perfect but it will load the pages 90% of the time but ping results to the DHCP and DNS (separate servers) are intermittent with a 50% - 75% loss rate, other times they will ping perfectly.  Pings to the gateway seem to always go through.  I am a little befuddled on what is going on.  I am leaning towards the switch that everything is connected to is having an issue but that'd be odd since its less than 6 months old... not impossible though.  Both servers are Windows 2008, the majority of the clients are Win7 and Win10. Any thoughts would be appreciated.  Thanks!

Hi

I have a requirement to block access into my Windows Server 2008 server on occasion from an IP address on the same subnet as my server.  On Linux, we can just set a null route and it stops incoming traffic into the server.  On Windows Server 2008, even when the null route is added, the other device can still communicate with our Windows server.  Is there any way around this please?

Say my server IP address is 192.168.0.10 and the device that I want to block access is 192.168.0.20 (on the same VLAN/subnet), on Linux I would issue the command:

route add -host 192.168.0.20 gw 127.0.0.1

On Windows, the command format should be as follows but it disables outbound comms from the server but not inbound comms to the server:

route add 192.168.0.20 mask 255.255.255.255 192.168.0.10 if 1

Please can someone offer advice?

Hi all,

I have 2 servers that have multiple NICs. 2 of the NICs have been connected directly with one-another and the others plug into switches.  i mapped a shared drive using the IP address of the directly connected NICs. When i copy files from one server to the other using this mapped drive windows seems to be using all the NIC's to transfer the files and not the NIC and IP address that was used to map the drive. Normally this would not be a problem, however as i am transferring over 2TB of data, my network is being slowed down because the data and sent over the switches as well and not just over the directly connected NICs. Is there a way to force server to only use the mapped link? I specifically used the IP address and not the machine name to try and prevent the use of multiple NICs.

All help would be appreciated.

Regards
Bernard

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.

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/
