Window 2008 R2 datacentre server time problem

Hi Team,
I have one window 2008 R2 data centre server, which having time problem, I have setted IST time zone but time coming 15 minute delay, I have tried to correct time by manual but time goes again 15 minute delay itself.
Please guide how to solve it and but i don't want to use NTP, as this server is on workgroup.

Hi ,
I followed following step to build NTP in window server 2008 R2.
Enabling & Configuring NTP Server
1. Change the server type to NTP.
Click Start, click Run, type regedit, and then click OK.
Locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type
In the pane on the right, right-click Type, and then click Modify. In Edit Value, type NTP in the Value data box, and then click OK.
2. Set AnnounceFlags to 5.
Locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\AnnounceFlags
In the pane on the right, right-click AnnounceFlags, and then click Modify. In Edit DWORD Value, type 5 in the Value data box, and then click OK.
3. Enable NTPServer.
Locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer
In the pane on the right, right-click Enabled, and then click Modify .In Edit DWORD Value, type 1 in
the Value data box, and then click OK
4. Specify the time sources.
Open a command prompt and type the command as below: w32tm /config /manualpeerlist:peers /syncfromflags:manual /reliable:yes /update
peers: time.windows.com or time.nist.gov
eg: w32tm /config /manualpeerlist:time.windows.com /syncfromflags:manual /reliable:yes /update
5. At the command prompt, type the following command to restart the Windows Time service, and then press Enter:
net stop w32time
net start w32time
i run following useful command.
1. To resynchronize time : w32tm /resync or w32tm /resync /rediscover
2. To verify the configuartion : w32tm /query /configuration and w32tm /query /status
3. Display the current time zone settings : w32tm /tz
Now what problem i am facing , when server goes restart "Window time service stoped" and ntp corrupted.
Even Window time service is set automatically, when i do configure again then NTP work proper.
Please help how to resolve this problem, if server restart NTP goes corrupted becuase of window time service stopped.

Windows 2008 R2 File Server - user profiles appear underdirectory C:\user

I've a windows 2008 r2 file server and few day ago I've noticed that under directory c:\users some user profiles have been created.
These users don't have rdp access to this server and don't use any ts application.
Is this a problem or a normal behavior?

Hello,
IIRC this is normal behavior as they do a connect to the server to access the shared folders.

How to activate Windows 8.1 on a Windows 2008 R2 KMS server when I don't have Windows 2012 R2 kms host key

I only have windows 8.1 kms host key but I can't add a client OS kms key to Windows 2008 R2 kms server. And I don't have Windows 2012 R2 license either. Is there any way I can activate Windows 8.1 using my existing kms server? Thanks.

I would like a yes no clarification answer. So does this mean that EVEN WITH THE PATCH. My Server 2012 Standard edition that currently hosts KMS VA for clients running Win7, Win 8, Office15, Server 2008, Server 2012. Will not be able to host windows 8.1?
I will have to install 8.1 and use as a host?
if you have a KMShost product key for WS2012R2, you can patch a down=level Server and be fine.
(the OP didn't renew SA or otherwise has no KMShost pkey for WS2012R2)

I'm having similar issues and have a similar question that doesn't seem to be answered:
My KMS server is Windows 2008 R2 (Also is my domain controller). I want to activate Windows 2012 R2 and Windows 8.1 machines off this KMS server. I can install the 2012 R2 key just fine but receive error 0xC004F015 (The Software Licensing Service reported
that the license is not installed) when I try to install my 8.1 KMS key.
What I'm gathering from this thread is that I have to set up a Windows 8.1 host and set it up to be a KMS server exclusively for activating Windows 8.1. Is this correct? If so, Microsoft needs to fix that. I have a SERVER for activations for a reason: it
is a server, not a client. If I am mis-understanding, how do I get my Windows 2008 R2 server to accept the Windows 8.1 KMS key for activating 8.1 clients?
Thanks!
You don't need Windows 8.1 KMS key. Your 2012 R2 KMS key will be able to activate your Windows 8.1 machines. So your current set up is fine, no need to set up another Windows 8.1 KMS host.
My problem is I don't have 2012 R2 KMS key as I didn't buy any Windows 2012 R2 license. So I can't use 2012 R2 KMS key to activate my Windows 8.1.
Oh that's interesting. I guess I need to play around more because my 8.1 test machine isn't activating. I'll start a new thread for that if needed. Sorry for the confusion.

Hi.
I think I solved this yesterday. We got 1 printserver, with an alias, which we had this problem to connect to. I noticed that there is a difference between x86 and 64bits system entries in the registry...
When you are having a 64bit system, you must use REG_QWORD instead of REG_DWORD, REG_DWORD is only to be used in x86 system! See below.
Windows 2008 server R2 64-bit
HKLM\SYSTEM\CurrentControlSet\Control\Print
= ”DnsOnWire” = REG_QWORD Decimal = 1
(reg add hklm\system\currentcontrolset\control\print /v DnsOnWire /t REG_QWORD /d 1)
HKLM\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters
= DisableStrictNameChecking = REG_QWORD Decimal = 1
(reg add hklm\system\currentcontrolset\services\lanmanserver\parameters /v DisableStrictNameChecking /t REG_QWORD /d 1)
HKLM\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters\
REG_SZ = OptionalNames = “aliasname” (C-name record in DNS)
(reg add hklm\system\currentcontrolset\services\lanmanserver\parameters /v OptionalNames /t REG_SZ)
Windows 2008 server x86
HKLM\SYSTEM\CurrentControlSet\Control\Print = "DnsOnWire" = REG_DWORD Decimal = 1
(reg add hklm\system\currentcontrolset\control\print /v DnsOnWire /t REG_DWORD /d 1)
HKLM\SYSTEM\CurrentControlSet\services\Lanmanserver\Parameters = DisableStrictNameChecking = REG_DWORD Decimal = 1
(reg add hklm\system\currentcontrolset\services\lanmanserver\parameters /v DisableStrictNameChecking /t REG_DWORD /d 1)
HKLM\SYSTEM\CurrentControlSet\services\LanManServer\Parameters\ REG_SZ = OptionalNames = “aliasname”
(C-name record in DNS)
(reg add hklm\system\currentcontrolset\services\lanmanserver\parameters /v OptionalNames /t REG_SZ)
Don't forget to reboot your system after these changes!

MacBooks can't resolve printer name when sending job to windows 2008 R2 print server.

So I am work at company in a windows server 2008 r2 and we have a windows 2008 r2 printer server. Our macbook pros are not on the domain so every time we print to the server we have to type in our credentials.
MacBooks can't resolve printer name when sending job to windows 2008 R2 print server while on wifi but works when hard wired. Any thoughts? The error message I receive is "invalid printer name". I've tried adding the printer through the advanced tab in the print and scan tab of system preferences. I add it buy smb://servername/printername.
When I tried to print on the wifi at my office I get "invalid printer name" in the print job status que.
We can just do direct printing but I would like to know if anyone has had this issue before and if you could point me in the right direction. Thanks!

I assume you aare using exchange when configuring the email notifications? What I would do is just use a normal IMAP & SMTP account such as Outlook.com or if you use a POP connector for exchange, one of those accounts' SMTP settings.
For example, I have a POP connector installed and my emails are hosted at 1and1. What I would do here is put my 1and1 SMTP settings in and use these, instead of using Exchange.
Let me know if this is possible.

Windows 2008 R2 Terminal Server.

Hi,
I was wondering about running Adobe Acrobat Std X (10) on a Windows 2008 R2 Terminal Server for two users. Anyone else that have any experience with this? Best solution?
Best regards
Vegard

Although Server 2008 R2 is a supported install platform, you'll have to be extremely careful about licensing - Acrobat is not a server product, so the only person who would be legally permitted to connect to it would be the one who owns the copy of Acrobat in question. Sharing a copy between multiple users is not an option; for that there are dedicated server-based solutions such as LiveCycle.

How to add Windows 2012 R2 RDS to Existing Windows 2008 R2 Terminal Server

I currently have a Windows 2008 R2 Terminal Server running and I am looking to add a Windows Server 2012 R2 server to it. All I see when I google the setup is only for Windows Server 2012 R2 RDS, cant find anything to integrate with a current 2008 R2 Terminal
Server.
Can anyone help with this or point me to a blog I possibly missed?
Thanks.

Hi,
Thanks for your comment.
Yeah, agree with diramoh; as already commented. If you want user session from RDS Server 2012 R2 then you need to install RDS License role on server 2012 R2, purchase and install RDS CAL (per user or per device) according your requirement and then you
can use user session for server 2012 R2 and also for lower version.
But as you already have Server 2008 R2 RDS CAL, then with that you can simply access lower version but can’t manage Server 2012\R2.
For more information, you can refer following document.

Windows Server 2012 R2 Remote Desktop Services
Hope it helps!
Thanks.

2008 R2 Server Time problems - Gaining/Losing 6s/min

I'm having problems with a server on our network. I can go for days without a problem but then without warning the server will either gain or lose time at anywhere up to around 6 seconds per minute. The server is running Server 2008 R2, member
server, IIS running internal sites, SiteCore CMS v6.4.1.
The w32time service is configured as follows
PDC - retrieves it's time from uk.pool.ntp.org, all other DCs and member servers have the w32tm service configured to syncfromflags:domhier.
The server in question is a virtual machine running on a server 2012 Hyper-V cluster. All of the virtual servers on there have the Hyper-V time sync service enabled however we have edited the registry to set HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\VMICTimeProvider\Enabled
to 0.
w32tm /query /source responds with a DC local to the server.
I've been monitoring the server for a number of days by outputting the following command to a file on the server w32tm /stripchart /computer:localdc /dataonly and on the whole the server has been within +-5 seconds of the reference computer.
At approximate 13:06 this afternoon the server started to lose approximately 0.1s every second and is still doing so. I've tried running the following command w32tm /resync /computer:localdc /nowait but to no avail. I've had to manually change
the time in order to get services available again.
I've searched through the event logs on the server at or around 13:06 and can't find anything of any significance happening at that time. I'm unable to restart the server during work hours as it's got key services running on it.
Any help on how to keep the time in sync on the server would be appreciated.

I would recommend that you read the Wiki I started here: http://social.technet.microsoft.com/wiki/contents/articles/18573.time-synchronization-in-active-directory-forests.aspx
As I mentioned:
Microsoft do not guarantee and do not support the accuracy of Windows Time Service between nodes on a network as this service is not a full-featured NTP solution that can meet time-sensitive application needs. Windows Time Service was not designated in such
way that it maintains time synchronization to the range of one (1) or two (2) seconds.
If you have an application that needs to have a high accuracy NTP solution then Windows Time Service should not be used in this case. Instead, third party software are available to satisfy this need.

Thanks for that Mr X, I have already been on that page and implemented the Windows time service in the manner described in the article and in the other articles relating to configuring the Windows time service in a Hyper-V environment.
The issue is not relating to the configuration of the service as a whole as my other 72 server instances are working fine, it is just this one that is giving me a problem. I have no need for a high accuracy environment, just one that keeps general
time and doesn't lose or gain 6 seconds/minute at random intervals through out the day.
I have been doing some further problem analysis since my original post with regards to the Hyper-V time sync service and my results are as follows.
When the time is a long way out on the server restarting the Hyper-V time sync service resets the time to the correct time instantly.
If you live migrate the VM to another host in the Hyper-v cluster when the time is incorrect, again the time resets to the correct time instantly.
I have reinstalled the Hyper-V integration services but this has had no effect on the problem.
As a last ditched attempt to resolve the issue I have re-enabled the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\w32time\TimeProviders\VMICTimeProvider
registry key so that when you run a w32m /query /source command the result is "VM IC Time Synchronization Provider"
I'll report back my findings.

Time Zone Redirect Doesn't work on Windows 2008 R2 Terminal Server

Hello All,
A client has two Windows 2003 and two Win 2008 R2 Terminal servers.
When users from a different time zone login to the Win 2003 server, the time zone of the server changes to reflect their own time zone.　 However when they login to the Win 2008 R2 servers, the time zone on the server doesn’t change.
I already enabled the "Allow time zone redirection" on both Win 2008 R2 Terminal Servers in :
Computer Configuration\Policies\Administrative Templates\Windows Components\Terminal Services\Terminal Server\Device and Resource Redirection
Yet when the clients login to the 2008 server and checks the time on the server, it still shows local/server time and not their own time zone.
Any input will be appreciated.

OBIEE install problem on Windows 2008 R2 64bit server

Hi!
I have for 1 month struggled with a OBIEE 11g install on a Windows 2008 R2 64 bit server. (I have a open SR at Oracle but have not got any answer/suggestion for 2 weeks)
I follow these documentations:
Oracle® Fusion Middleware
Installation Guide for Oracle Business Intelligence
11g Release 1 (11.1.1)
E10539-01
and
http://download.oracle.com/docs/cd/E14571_01/bi.1111/e10539/c4_installing.htm#CIHDJGIH
Specially chapter 4.4.4 for the moment, cant get pass step "Specify Installation Location"
First did I run RCU against our Oracle 11g database and created the schemas for BI Publisher
Then did I install JRockIT - jrockit-jdk1.6.0_26-R28.1.4-4.0.1-windows-x64.exe
Then from JRockIT installed WLS_1035 generic.
Then configure AdminServer so thatone is up and running (even installed a HTML server from E1 to check if WLS is up and running and working)
Then start the installer (Oracle Business Intelligence, v. 11.1.1.5.0, for Microsoft Windows x86-64-bit) disk 1, setup.exe, then must I choose "software only" install. But on step 3 och 9 can I not press next, the installer says that I do not have any "Application Server" running. I have installed on E:\Oracle\Middleware but the installer can not see any application there, but I can access it thru a browser.
Tests I have done,
Install loopback adapter
Deinstall loopback
Deactivated everything but IPV4 protocoll (we have also IPV6 on all server).
Verified that we have static ip on the server
Tried installer for BIP (OBIEE) with WLS AdminServer running and without have it running.
And checked the installer logs everytime, no errors, no warning.
Is there anyone how can guide me or give some tips? I am getting frustrated after 4 weeks without success.
Best regards,
Anders

Hi!
It is the installer who not working properly, when using the "Browse", I had to choose a comletly wrong place first, and then again choose the correct installation path, after that would the understand where I wanted to install.
Best regards,
Anders

Windows 2008 R2 KMS server not activating Windows 8.1

We have a 2008 R2 server running VAMT 3.1 and with KB2757817 installed. I added our Windows Server 2012 and Windows 2012 R2 KMS product keys to the KMS host as well as our Windows 8.1 KMS key, and restarted the system.
So that when I look at the list of Product Keys I see the following keys:
Windows Server 2012 RTM ServerDataCenter;ServerStandard;ServerMultiPointStandard;ServerMultiPointPremium Volume:CSVLK
Win 8.1 RTM Enterprise;EnterpriseN;Professional;ProfessionalN Volume:CSVLK
Windows Server 2012 R2 RTM ServerDataCenter;ServerStandard Volume:CSVLK
Windows Server 2008 R2 RTM Std and Ent Volume:CSVLK (KMS_B)

I then go to one of our Windows 8.1 systems and run the following commands:
cscript c:\windows\system32\slmgr.vbs /skms <servername>
cscript C:\windows\system32\slmgr.vbs /ato
and I get the following error message:
"Error: 0xC004F074 The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information."
Meanwhile Windows 7 clients still activate without a problem.
On the KMS host I run slmgr /dlv and get the following:

Did I miss a step in adding the 2012 R2 KMS key, and if I did what step did I miss?
It's not possible to add Windows Vista/7/8.0/8.1 KMShost pkeys into a WindowServer OS - they will not install, because the KMShost pkey must activate the host OS as well as perform KMShost functions, and, a WindowsClientOS pkey will never be accepted on
a WindowsServerOS.
Similarly, you can't install multiple Windows pkeys - only the last (acceptable) pkey will be kept - all previous pkeys will be displaced/removed (last in wins).
Your slmgr output clearly shows that you have the WS2008R2 KMShost pkey, in place. You need to install the WS2012R2 KMshost pkey to get your 8.1 KMSclients to activate.
KMShost pkeys are "cumulative", i.e. WS2012R2 KMShost pkey will activate all lower versions of both WindowsServer and WindowsClient OS.

BSOD Error Windows 2008 R2 Terminal Server

Hi guys
I have a unique issue on a Windows 2008 R2 Enterprise Terminal Server where it keeps blue screening every so often (from every 2 or 3 days to some times once a week) with the exact same BSOD error. After countless hours Googling and researching I am simply
at a dead end and desperately require some guidance if possible. I have ran malware bytes and other tools and the TS does not have any malware or viruses. I have ran a chkdsk and everything is also okay with that.
It has happened about 5 times now with the same errors every time:

Hi,
Thank you for posting in Windows Server Forum.
The problem which you are facing seems to be due to ntoskrnl.exe. There might be some corruption in ntoskrnl.exe file.It’s responsible for various system services such as hardware virtualization, process and memory management, thus making it a fundamental part
of the system. It contains the cache manager, the executive, the kernel, the security reference monitor, the memory manager, and the scheduler.
Please check below articles to fix the issue of ntoskrnl.exe.

Windows 8.1 Enterprise DirectAccess with a Windows 2008 R2 DA server

I don't suppose anyone out there is using Windows 8.1 Enterprise with a Windows 2008 R2 DirectAccess setup?
We have an existing 2008 R2 DA setup used by 50+ Windows 7 Enterprise laptops without any issues.
We're testing Windows 8.1 Enterprise and the DirectAccess functionality seems to be very intermittent, you can't use any of the Windows 8.1 powershell commands to look at the status as it's not using the new 2012 functionality but DA is there and works.
The problem is it seems to take a long time to connect, anything from 15 minutes to several hours and in some instances seems to fail to connect entirely. I can't see anything in the event logs and I'm really struggling to work out why it's so intermittent.
Cheers
Robert Grigsby

Hi,
DirectAccess performance is dependent on many factors such as the speed of the DirectAccess client’s connection to the Internet, Internet latency and congestion between the
DirectAccess client and server, and the current load on the DirectAccess server. Another reason might be the type of Internet Protocol version 6 (IPv6) encapsulation being used over the Internet Protocol version 4 (IPv4) Internet. 6to4 and Teredo tend to have
higher performance because the encapsulation is simpler to process. Internet Protocol over Secure Hypertext Transfer Protocol (IP-HTTPS) tends to have lower performance because of the higher protocol overhead and the additional Secure Hypertext Transfer Protocol
(HTTPS)-based encryption and decryption.

ipconfig command on the DirectAccess server, which indicates the type of encapsulation based on the interface that has a global IPv6 address assigned.
