Server isolation at Network Level

We have a set of MS servers that cant be upgraded anymore and will be soon End of Support. Hence this would leave our network vulnerable to exploits and other infections.
Hence as a workaround we are looking for isolation technique at the network level. Could you please suggest a suitable one ?.
Two options that i am considering now are
1. Putting the affected servers in a separate VLAN.
2. Configuring PVLAN.
Please give me your opinions. Any help on this is very much appreciated.

Thanku All,
I have done all the steps as you mentioned
1. Activated the business function OPS_PS_CI_1.
3
2.
3.
Activated Multiple Plan Version using the tcode RCNPRECP
Still not able to view the options under SPRO-IMG Easy Cost Planning
* Create Alternate CO Version
* Activate Multiple CO Version
Also not able to implement ECP at network level.

what is the "sql server isolation levels" what is the main use of those isolation levels,
can you please give the definition of sql server isolation level.
how it internal works?

Remote Desktop Connection - Windows Network Level Authentication

Hi
I'm trying to find a piece of Remote Desktop "Manager" software for Mac which supports Network Level Authentication (NLA). When NLA is enabled on a Windows Server I am unable to connect via CoRD or Royal TSX.
The reason I say "Manager" is because I have many, many windows servers I need to connect to and so I like to use software such as the above to save a list of all the servers for ease of access - this saves me having to type in the name of the server each time.
At the moment, for those servers with NLA enabled, I have to fire up Remote Desktop Connection for Mac and enter the name. I realise I could save this each time but then I would have LOADS of shortcuts.
Any ideas/proposals on pieces of software that can cater for this?
Thanks!

Hi!
Royal TSX actually supports NLA but you have to use the FreeRDP plugin instead of CoRD and enable the setting in the advanced settings of your RDP connection.

AD "Log on to" restriction causes RDP connections with network level authentication to fail

I am running a Server 2008 R2 environment and have recently enabled network level authentication for RDP connections. Since the change, users who have their logons restricted to specific servers via AD, now get an error when logging on via RDP:
An Authentication error has occured
The Local security authority cannot be contacted
After investigating this error and reading technet I found that removing the "log on to" restriction within their user object solved the problem even tho they had rights to this server. Adding the users client PC name to the "Log on
to" list also solves this issue.
My question is, is there another way around this? We have an environment where some users may require an RDP connection from a client PC not on the same domain (over VPN) as the server. It will not be practical to add many different client PC names
to the log on to list and I don't understand why client PC's must be specified in the Log on to list and not just the actual server they are logging onto.
Any pointers appreciated

I have just come across this problem on one of my client’s domains; they have recently enforced a policy to “Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure)” and users with “Log on To” restrictions
on their account are no longer able to RDP using their second account.
After a lot of fiddling around I finally resolved the problem by adding the connecting computer name into “Log on To” list. Ultimately it appears that Network Level Authentication (NLA) requires authentication to take place on both the host initiating
the connection and the remote host.

Configure Network Level Authentication for Remote Desktop client

We publish Remote Desktop in our Windows 2008 R2 terminal server.
However, in Windows 2008R2 , the remote desktop client will a lillte bit slow
I found out that if I modify the setting in default.rdp
authentication level:i:0
enablecredsspsupport:i:0
it will increase the speed a lot
however, how can I set all user use remote desktop will disable those feature as well?
Thanks

Hi Kenneth,
I suggest you to see similar thread "disable
Network Level Authentication Terminal Server 2008"
If above thread does not helps, seek help from RDS/TS experts in here.
Or wait until any of our moderator move this post to respective forum.
Thank you for understanding.

NLA Disabled. Still can't RDP; "requires Network Level Authentication"

Had a server I could RDP onto without any issue running Hyper V.
I removed the Hyper V role.
I then rebooted and attempted to RDP onto the server and can't:
The remote computer that you are trying to connect to requires Network Level Authentication (NLA), but your Windows domain controller cannot be contacted to perform NLA. If you are an administrator on the remote computer, you can disable NLA by using
the options on the Remote tab of the System Properties dialog box.
OK... Never needed before.
I checked the network settings remotely with netsh and confirmed correct DC as DNS. So I'm scratching my head why Microsoft are lying to me?
OK, so I check the NLA settings remotely, sure enough is enabled. So I disabled via remote registry, reboot the machine, confirm the registry is set to NLA disabled again remotely and attempt to connect.
And... Same message.
I can access any other of the 2012 R2 servers on my domain without issue. I can open AD or any other Domain tools from other servers with the same DC as the problem server as their primary DNS.
How can I get that message when both the DC is contactable and NLA is disabled?
How did removing a role cause this BS suddenly?

Hi,
Thank you for posting in Windows Server Forum.
Which version of client RDP you are using?
You can use RDP v8.1 for better performance.
Apart from above, Use local admin account to log on to the virtual machine and set the DNS to point to your DC. Alternatively, assign the IP address of the DC/DNS under DNS servers of virtual network.
Also when trying to remote desktop check the option “Allow connection from computers running any version of Remote desktop (less secure)” under system properties.
Hope it helps!
Thanks.

Network Level Authentication

We have enabled Network Level Authentication on all of our test servers. We are now having issues with 2 servers where folks are receiving an error stating that the remote computer Network Level Authentication which your computer does not support.
All clients are Windows 7 SP1, and can access other servers that have Network Level Authentication.
When comparing the servers to working servers, there doesn't appear to be any differences.
Any Ideas?
DJ

Hi DJ,
From the current description it seem is the self-signed certificate corrupt, please perform the following action, open the Certificate Management mmc snap-in with the Local
Computer account. You will find the self-signed certificate in the 'Remote Desktop' store of the server.
Delete the certificate here.
For Windows 2003/ 2008, a server restart is required for this certificate to be re-generated.
On Windows 2008 R2, you can restart the Remote Desktop Services Configuration service to get the certificate re-generated.

Remote Desktop Network Level Authentication

Recently, I began getting failed connections from a Windows 7 Enterprise client to another Windows 7 Enterprise host where the host is requiring NLA. This has been a problem on and off for YEARS and I have found no link that can tell me to configure something
that I haven't already configured. Neither system underwent any configurations changes that I know of with the exception of Windows security updates/patches. In fact, some people in my company have the same issue while other do not. I can find no rhyme or
reason to it. Heres where I'm at:
"The remote computer requires Network Level Authentication, which your computer does not support. For assistance, contact your system administrator or technical support."
But I do. when i click the upper left hand corner of my RDP client window and select "About", I see this:
"Remote Desktop Connection
Shell Version 6.1.7601
Control Version 6.1.7601
Network Level Authentication Supported.
Remote Desktop Protocol 7.1 supported."
And the above info is exactly what it says on the host.
Here's the SecurityProvider registry settings on the client:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders]
"SecurityProviders"="credssp.dll"
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SaslProfiles]
"GSSAPI"="Kerberos"
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL]
"EventLogging"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Client]
"DisabledByDefault"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\WDigest]

"Negotiate"=dword:00000000
"UTF8HTTP"=dword:00000001
"UTF8SASL"=dword:00000001
"DigestEncryptionAlgorithms"="3des,rc4"
Every link I have looked at tells me to look at those things. Anyone got something new? :)
Also if someone knows how to log the RDP failures that would be cool too. Presently I have turned on Audit Other Security Events in GPO but it doesn't tell me if someone attempted to authenticate with a less then desirable security protocol.
As a fix, for now, I have reduced the security requirements on the host to not require NLA. <-- This is the only consistent fix I have ever seen that works.
By the way, just about every link I see also starts talking about setting up RD session host service. I am not running Windows Server 2008. This a Windows 7 to Windows 7 problem

Hi,
On both Windows 7, Please go to System Properties,
Remote tab and make sure that Allow connections only from computers running Remote Desktop with Network Level Authentication
is unchecked.
If problem persists, please check if there was any Windows updates need to install, if so, try to install updates for test.

What changes occurred in version 8+ of itunes at a network level

Hi all
I am very desperate to solve a problem that has been nagging me for nearly two years now. Any PC in my network (Belkin wireless router / Hub) that tries to connect iTunes 8+ to airport express using a wireless card instead of Ethernet to the hub does not work. I get an error 15000 and no sound.
Version 7.7 - is OK but i cannot talk to my shiny new iPhone with that version...
EG. I upgrade to version 9 and loose my connection to the airports. I take the pc to the Belkin router and plug it with an Ethernet cable and it works fine to the airports... every thing else is OK just kills wireless streaming.
Given that i have been scouring any posts going and tried EVERYTHING... I can conclude that Itunes 8+ versions have a fundamental change that kills of air tunes streaming only through wireless network cards.
My question is that only what is the basic network level change in itunes 8+

Cannot connect to my Server across my network

Hi
I have a Mac Mini with Snow Leopard Server preinstalled.
At this stage, I need my server only to be available on the local network and I am not part of a larger organisation. We have run an informal network in the past through our wireless router but want to use the server within this network mainly for file and print sharing, calendar, contacts and wiki sharing.
So, the network is as follows:
Wireless router provides access to the outside world, and provides IP addresses as subnets to the other macs and PCs. All the machines can see each other currently and can share files (permission dependent of course).
I have setup the new server and it has been given an IP address by the router. When asked to provide a domain name, as we don't currently want to point our internet domain towards this server, I followed the suggestion in the Getting Started guide and entered myserver.private.
I have activated all services except mail and VPN as I don't intend to host my mail internally and I am not ready to use VPN just yet.
All the other machines can now see the server - its name shows on all the finders and explorers. However, when we attempt to connect to it, Finder reports Not Connected.
The admin user for the server is the same as my user on my iMac, but when I attempt to connect my user to the server from the iMac (via the Accounts dialog in System Preferences setting Login Options and connect to Network Account Server), I receive an error stating that the server name cannot resolve. The error number is 2200 - Could not resolve the address. I have tried putting the IP address of the server in as well as the name, but no joy.
What am I missing? What else do I need to do?
Thanks in anticipation. Used to support Unix servers machines in the early 90s. But can't remember!

Here's what worked for me. Sounds like my office is similar to yours.
By default, the router acquires DHCP onfo from the ISP, including the address of the ISP's DNS servers. By default, each workstation acquires DHCP info (including DNS addresses) from your Router. That means that by default, your workstations contact the ISP's DNS servers directly. Nothing is telling them about the existance of your server, and many of their functions won't see it and won't work properly.
You have a choice, you can manually configure each workstation to point to your server for their DNS, or you can manually configure the router to hand out your server's address for DNS.
I prefer the second option, since it requires zero configuration of the workstations, which also means that any time a new workstation comes into your office (laptops, iPhones, etc.) the system just works. Less deskside support burden for you. The workstations contact the router for their DHCP handshake, and are told by the router to contact your server for all DNS inquiries.
On the server, obviously, you need to make sure that DNS is working correctly. That includes, manually entering your ISPs DNS servers (or any other DNS server you trust, like OpenDNS, Google DNS, etc.) in the Server Admin DNS Settings as the lookup servers (these go in the confusingly named "Forwarder IP Addresses"). Entering multiple external internet DNS servers in this box is acceptable, so you have some "failover" abilities.
Also, on the server, in System Preferences, you should manually configure the DNS options to point to the server itself. That means that when any random process running on the server needs a DNS lookup, it will use the DNS server running on the server to resolve it.
The downside of this approach I have described above is that if your server is ever shutdown, none of the macs will "see" the internet. Their macs will go to your server for their DNS inquiries, and receive no response, and get strange errors (timeouts). It means taht if you ever have to do server maintenance, you'll probably have to do it on nights or weekends, or temporarily change your router's DNS settings to point to the outside world DNS servers while your own server is down, and then change the router back afterwards. My server uptime has been very good so far, and this hasn't been a problem at my office.

I have a Mac on my home network and also a Systemline music server on same network. My PC was able to find the server but my MAC cannot. I can ping the server from the mac, but cannot actually connect . Also can't add the mac as a location from server

I have a Mac on my home network and also a Systemline music server on same network. My PC was able to find the server but my MAC cannot. I can ping the server from the mac, but cannot actually connect . Also can't add the mac as a location from server, despite following the Systemline instructions that impy this can be done.
Can anyone please advise what I am doing wrong?

Hi LowLuster
Thanks for reply. I am not an expert on these sharing protocols but I think I have turned on SMB sharing but still wont connect. I tried adding netwrik drive by using cntrl K in finder and using smb\\network address but nothing. It is driving me mad!!

How do I get connected to a server on my network via an IP address? When I try to open in a URL and login as a registered user with proper login it errors out saying there was a problem with connecting to the server?

I am new to Mac...How do I get connected to a server on my network via a hyper link IP address path? When I try to open in a URL and login as a registered user with proper login it errors out saying there was a problem with connecting to the server?

Some of the following is going to use some technical terms — this area is inherently somewhat technical.
If you don't understand some part of the following reply, please ask.
Is this your own OS X Server system on your own network, or is this some other server within some larger organization?
You're posting this in the OS X Server forum, which is a software package that allows OS X systems to provide web-based and many other services; to become servers.
If it's your OS X Server on your network, then the network and DNS configurations are suspect, or the server is somehow malfunctioning or misconfigured. This is unfortunately fairly common, as some folks do try to avoid setting up DNS services.
If it's a larger organization and somebody else is managing the server and the network, then you'll probably need to contact the IT folks for assistance; to learn the network setup and DNS requirements, and if there's a problem with the server itself.
The basic web URL "hyper link IP address path" — without using DNS — usually looks something the following, where you'll need to replace 10.20.30.40 with the IP address of your server:
http://10.20.30.40
UptimeJeff has posted a URL that specifies the AFP file system; an OS X file share. That's used if you're connecting to an Apple storage service somewhere on your network. You might alternatively need to specify smb://10.20.30.40 or such, if it's a Windows file server. (There can be additional requirements for connecting to Windows Server systems, too.)
If there's local IT staff available here, please contact them for assistance. If these are your own local systems and your own local OS X Server system, then some information on the server will be needed. (If you're on a NAT'd network, you'll also need to get DNS services configured and working on your local OS X Server system and your network — you'll not be able to skip this step and reference ISP DNS servers here — or things can and usually will get weird.)

Unable to caluclate cost in CJ20 for wbs and network level.

Hi All,
I have a query in the project Builder(CJ20N).
I created Project>WBS Elements>Network> and posted costs via assigning activity.
If I select an activity and go to edit>Costs, the "calculate costs" option is activated. ( I get "Message Costs were calculated: See menu Edit -> Costs -> Planned - Actual")
And also I am able to view the cost in Edit>Costs> Plan/Actual.. "Activity/Element". Please see the screenshots of Plan /actual comparison.
However if I select the WBS or Network and go to edit>Costs, the "calculate costs" option is disabled (frozen) and also in the same path Plan/Actual> "activity/Element" option is disabled (Frozen).
Request you to review the attached screenshot and advise is there any way to defreeze the option "calculate costs" and view the costs in WBS and Network level?

Hi,
why you want to see plan cost in project builder CJ20n? any specific reason please let us know...
every structure report having this kind of feather as CN41n/CNS41 then check these two report.
and lots of hierarchical report is there for seeking plant cost in project as Gokul suggested above.
so in project builder only plan VS actual cost can be look like by network activity.
