Dear Experts,

I need your opinion on this question we have. Currently We host a SaaS environment for our customers. Due to a lot of legacy our SaaS environment is connected to the same domain controllers as our internal network and computers. Everything is very open and security is becoming a real issue. Now the question we struggle with, what is the best thing to do.

1. We completely separate our SaaS environment from their current domain. Create a new domain with its own forest. Only the administrators get a username and password in this new forest. This will make sure none of my employees can access the SaaS environment without an administrator knowing about it (which is what I eventually want to achieve).

2. We keep the the SaaS environment and our own network in the same domain and forest, and we block any access for my users to the SaaS environment based on firewall rules, leased privileged user account, and audit policies.

I don't quite know what the best option is, both bring a lot of configuring and after work hours to implement. We just want a secure environment for our customers which is compliant with ISO 27001.

Here is the method that I have in mind :

First thing : The server has 5 NIC, 1 for management and 4 others.

Here is my method:

1: Detect the correct four
2: Go to server manager  => local server => NIC team (set on disable) ==> Chose  Task ==> New  team.
3 : Select the 4 network cards, give a name and then create the team. (now nic teaming should be eneable)
4: Now set an IP adress to the new NIC Team card (As i don't have DHCP)
5: After that, go to hyper-v setting, create an new virtual card with the New Nic Team Card
6: select the new virtual card for the virtual machine
7:Now everything should have an IP and go to net . Right ???

Thanks for your help.
I got problem, to put all 4 files (as attached) into one FTP site, that not all files can be successfully processed. But there is no problem at all, if I one by one, put the file, there is no problem to process all files. What can be the reasons to this?
Hi All,

we are doing a project in which we are upgrading all windows 2008 domain controllers to windows 2016 server (VMs)
The one which will be done first have NPS role, and is a certificate server as well (doesn't hold any FSMO roles)
any guidelines which can assist in the upgrades and demoting the old server?

Hello - I have a Windows 2008 R2 server that I built recently, and in the first week of use, it has lost it's trust relationship with AD twice.  What causes this?
We had this problem start suddenly 3 - 4 months ago and still can't track it down.  We have Sharp MFD's:  models, MX-3100N, MX-M453N, MX-4111N, which all intermittently, not often, give the user a "Network Error CE-00" error when scanning a document to a network share location.  They can wait a variable amount of time, try again, and it works perfectly.  This is using SMB.  
   We've tried updating the firmware and using the IP address, rather than the DNS name in the scanning configuration, with no success yet.  
   We understand that it is a network connectivity issue in some fashion but still can't track it down.  This is on multiple devices, so doesn't seem to be a hardware problem.  There weren't any other changes during that time period when it started happening.  Thanks for any thoughts on this!
Windows user, on a network when connected to the company network (including wifi), everything is OK, however when on an outside network, message pops up Windows Authentication failed, including Outlook. Can't connect to VPN either.
Hello Experts,
We recently moved from a Netapp 2040 (7.1) to a Netapp 3210 (8.1.4P10 7-Mode).

We've noticed a significant slowdown in CIFS when accessing files. Everything is the same network, software and server wise. We snap mirrored the data from the 2040 to the 3210, changed the name and IP of the 2040, rebooted and then gave the 3120 the name and IP of the 2040 and rebooted the 3210.

Everything looks fine except for two things:

1. when we ping the NIC on the 3210 the latency is around 14ms.
2.I have a file from a program we use to determine if things are slow and on the 2040 it would open in less than 5 seconds. on the 3210 it takes 1 minute and 30 seconds.

We are currently doing a snapmirror to another system but we didn't notice any latency when we snap mirrored from the 2040 to the 3120.

We use mainly RDSH servers (Windows 2012 R2) and Windows 7 workstations. We have one file (program built in house) and it doesn't seem to load any slower on the 3210 than it did on the 2040.

I'm running the netapp system analyzer for CIFS but i dont see anyting out of the ordinary. not sure if its a protocol issue or something else.
I'm sure this probably isn't possibly, but is there a way to map 2 different network drives to the same drive letter?
The only way I can see doing it is to change the drive letter for one of network drives. Suggestions?
I hope that someone can shed some light on my situation;

We have many RDP farms with terminal users using RDP with roaming profiles...

As users get exited from the company it seems that the user profiles on the actual rdp servers are just taking up space...

To try and help the person in our staff clean up these profiles when they process an exit for an employee I wanted to have a powershell script they can run, (this part works great) that will check all of our RDP servers and list the users with profiles on the servers, and then from the list you can highlight the user profiles you wish to remove & then hit delete & it will remove all of those profiles stored on all the RDP servers.. All of that works great with the script I have so far..

Here is the part I am trying to tweak.. to help ensure an active user profile is not accidentally deleted, or to run as a quarterly maintenance it would be nice to check each user with a profile on the RDP servers to see if the user is still in AD, now that part is easy... however in our org there are many users that do NOT have their roaming profile path (what the user profile is named on the RDP server) matching up to the actual user name in AD...

Here is an example

a user named tmizi has a roaming profile of \\some-nas\user-profiles\tmizimakoski  
So on the RDP servers my script says there is a user named "tmizimakoski" and in AD the user name is actually "tmizi"

There are others as well where the user's …

It's wired by ethernet right beside he router

Win 10

Two iPads and iPhone all fine on wireless - getting 80 meg fast broadband

PC - Every few days www speed start to crawl for unknown reasons

Can't change the router Dns so I changed the pc Dns to google and that fixed it one day .... now problem back and customer on the phone again

It's been scanned with Microsoft Sec Ess and super anti spy and probably malware bytes I think also

What to do next / what to try ?

Should I consider adding a new network card or updating driver on present one ?

The pc itself is fast enough on applications but www speeds are so bad occasionally when other clients are ok

Home setup with 80 meg connection ....
Hi, I have see one software, here is showing some error massage like "server refused" that time i make a ping to server & see when TTL=64 showing error massage but when TTL=128 that time no error.

Anyone have any idea?
When i go to another VLAN with my laptop, It will not get the connection from network or we can say it will take some time to get IP from new VLAN from old VLAN. If i connect the laptop from Wireless it shows connected.
I want the suggestions that i would be able to connect on diffrent VLANs with my laptop and with my netwrok.
Hi all,

We have a router on and our main server has 2 NIC's one has the IP address of which is the main IP address but the other NIC's IP address is 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 i get a few "reply from bytes=32 time<1ms TTL=255" (this is fine)  entries followed by "reply from 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 ?

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.
The following error has occured while joining to the domain xyz. the network path not found
I am getting this error while joining the windows 10 to windows server 2008 r2.
All the computers on the DC are working fine except when we disjoin and join new computers, we are getting this error.
Checked DNS-
DC is a single domain .
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:

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!

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?

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.
Microsoft PFE Remediation for Configuration Manager   breaks Lan\Wlan switching on HP 840G3.
HP 3LS has identified this SCCM Client health service as the problem that breaks auto-switching.
Has anyone else see this issue?
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.


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.

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.

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.

What did I miss ? Thank you in advance.
