W2K8r2 DC not serving clients
Problem Context:
4 DC's serving the domain (native W2K3), DC01, 2, and 3 are W2K3x32, DC04 is W2K8r2x64 (newly added).
All DC's are GC and DNS.
DC's all pass DCDiag with no unexplainable errors
LDAP query of the DC's in the site shows all 4, with identical weight
All DC's are in the same AD Site
No errors in any event log
Sysvol is visible from everywhere, for all 4 DC's
repadmin /replsum /errorsonly on all DC's (including 04) shows no issues that I don't understand (we have a remote DC in the forest offline, I see that one)
Each DC points to another DC for 1st DNS and itself for 2nd, in a chain (01->02, 02->03, etc)
All are single NIC, on different subnets.
I have 1500+ clients in my environment. DC01/2/3 are slated to be upgraded, DC04 is the first. It's newer hardware, 1gb vs 100mb, more ram, x64, etc. However, in removing the old 04 and adding a new one, DC01/2/3 went off the charts
on CPU/LSASS. Doing a query (nltest /sc_query:domain) of my environment, I show that 33% of the environment is divided up each to 01/2/3, 0% go to DC04. I have a script I run to "stir the pot" after I reboot a DC to "rebalance"
them, which is essentially an "nltest /sc_reset:domain" run on each server. I run this, and 33% end up on 1/2/3, 0% on 4.
If I do it by hand, nltest /sc_reset:domain\dc04, it works and the system uses DC04 and stays there, as expected, but if left to their own devices, zero systems choose DC04.
Help? I've no clue why this is happening. What happens when I replace DC01/2/3 with W2K8 DC's? Will the systems choose none of them? We're buried in CPU alerts and my proliferation is blocked until I can close on this.
Any wisdom would be greatly appreciated. Thank you.

3. I did, both at the root and child. The NS record only contains the 4 DC's, with correct IP's. The msdc's folder only contains the 4 dc's with corrct IP as well.
4. I have IP concerns posting the log file to a public forum, but going through it and checking the health checks on that site, the domain passes all tests, including the SRV test at the end. I even cycled through each DC on server= and re-ran the
query, from multiple clients, it returns the same info, the correct info, all 4 DC's, with the same weight.

regarding mountain lion server: clients experience intermittent service connections. the server system log has the following error- Client handshake failed (6):113: Server not accepting client connections. any suggestions would be greatly appreciated - thank you
Hi Jason
I was getting the same behavior after Apple support had me delete some plist files to get Airplay going. I was also getting the following error:
the error occurred while processing a command of type 'writesettings' in the plug-in 'server vpn'
I went into ~/Library/Preferences/ and /Library/Preferences/ and deleted every plist contating the word server. I had to re-set up my server (meaning walk through some intial steps) but all of my settings were still there after that and everything started working again.
Just a thought, obviously try at your own risk but it worked for me.

FU Ant task failure: java.util.concurrent.ExecutionException: could not close client/server socket
We sometimes see this failure intermitently when using the FlexUnit Ant task to run tests in a CI environment. The Ant task throws this exception:
java.util.concurrent.ExecutionException: could not close client/server socket
I have seen this for a while now, and still see it with the latest 4.1 RC versions.
Here is the console output seen along with the above exception:

Thanks,
TrevorI am not sure if this information will help everyone, but here goes...
For us, these problems with FlexUnit tests crashing the Flash Player appear to be related to couple of factors. Recently, we moved up from Flex 3.2 to Flex 4.1 as our development baseline. Many people complained that their development environment (Flash Builder, etc.) was much more unstable. Apparently, 4.1 produces SWFs that require more memory to run than 3.2 does? Anyway, we still had Flash Player 10.1 as our runtime baseline. Apparently, that version of the player was not as capable of running larger FlexUnit test SWFs, and would crash (as I posted months earlier). I upgraded to the latest 10.3 standalone player versions, and the crashes have now ceased. It would be nice to know exactly what was causing the crashes, but memory management (or lack of) is my best guess.
So, if you are seeing these issues, try upgrading to the latest Flash Player version.

JMS Internal Error at Server Client Adapter!JMS Service is not started
Hi
Can any one tell me how to trouble shoot for following errors:
Failed to Create Connection! Reason: Response from the server could not be reached.
JMS Internal Error at Server Client Adapter!JMS Service is not started
The following hosts could not be reached 143:223:221:10:50310
We are trying to send the request from SONICMQ JMS to R/3 and trying to post the response to Sonic Queue. but we are facing some problems for JMS adapter .
but in JMS sender and receiver adapter i gave different IP and port for listen the SONIC queue. why it is showing in different IP here? this message got from logviewer.
regards
Rambarki...Rambarki,
What is the error displayed on the Adapter Monitoring pages?
Generally the correct error descriptions for connectivity issues are found on adapter monitoring UI than any other.
Other possible reasons could be :
<i>JMS Service is not started
The following hosts could not be reached 143:223:221:10:50310</i> This might be issue with your network settings i.e. XI server is unable to reach the specified IP on specified port.

After installing Final cut server client on OSX 10.6.8 error: Apple QuickTime or the QuickTime Java component is not installed.

I have a few collections, but not all PC's in those collections are listed in "All Desktop and Server Clients". Does anyone happen to know the reason for this? It should have at least the same number of clients as the largest collection.
Thanks,
James
James A+, Network+, MCPHi James,
The All Desktops and Server collection only contains devices that show client=yes.
Meaning the Configuration Manager client is installed on those devices.
This WQL query will give you a collection of all devices that do not have the client installed.
select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System where (SMS_R_System.Client is null or SMS_R_System.Client = 0) and SMS_R_System.Name != 'Unknown'
Another handy collection is all clients that are inactive (No communication for the default 7+ days)
select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System inner join SMS_G_System_CH_ClientSummary on SMS_G_System_CH_ClientSummary.ResourceId = SMS_R_System.ResourceId where SMS_G_System_CH_ClientSummary.ClientActiveStatus = 0
I normally create both and then a third collection of all devices and exclude the above two which should show you all healthy devices.
Have a look at the ccmsetup.log file on the client if it has attempted to install the ConfigMgr client but failed. -
\\SERVER\Clients\Setup\setup.exe with Windows Vista Error
I added the first Vista client to an SBS 2003, SP1 domain. Until now, all clients were WinXP, SP2. Office 2003 is installed on the XP clients, and the Vista client, which may not be pertinent to this problem.
As is normal, "\\SERVER\Clients\Setup\setup.exe /s SERVER" is executed when a user logs on to any domain client. On the Vista client, I always get the dialog -- regardless of the account privilege -- asking for permission to run Setup.exe. It is annoying. Occasionally, the Program Compatiblity Assistant will appear and advise there's a known compatiblity issue with Setup.exe. It points to KB article 926505 for resolution. The title of the KB is, "Windows Small Business Server 2003: Windows Vista and Outlook 2007 compatibility update."
When I run the SBS2003SP1-KB926505-X86-ENU.EXE fix, I get the error: "This update cannot be installed. Either it is already installed as part of an existing service pack, or it requires a more recent service pack. For more information, see the systems requirements on the download page."
I installed Windows Server 2003 SP2 and run the KB926505 fix, but I get the same error "This update cannot be installed. Either it is already installed as part of an existing service pack" After a reboot of te SBS server the same problem on the Vista client, I always get the dialog -- regardless of the account privilege -- asking for permission to run Setup.exe. It is annoying. Occasionally, the Program Compatiblity Assistant will appear and advise there's a known compatiblity issue with Setup.exe. It points to KB article 926505 for resolution.
The problem is Windows Vista Business, because all windows XP clients have no problem at all.PNP,
You do not say whether if you accept the permission dialog whether the setup continues or not, but the short answer to the question revolves around UAC.
Remember that EVERY user (except the actual Administrator account) has only Standard user rights regardless of group. When a task that requires Admin rights is executed, one of three things will happen: 1) If you are THE Administrator, then your task will continue. 2) If you have Admin rights, you will be prompted that a process is trying to use elevated rights and ask for permission, or 3) If you are a Standard user, you will either be denied flatly or prompted to supply credentials. Which of these happen depend on GPO settings, but the default is to prompt.
In any event, I believe that this is what you are running into, and is one of the big feature improvements in Vista. Yes, it can be a bit annoying (Try deleting an "All Users" icon from the Start Menu!) but is there to place one more barrier between virus and malware writers and your OS.
If it's TOO annoying to bear, you can turn off UAC by going into your profile and disabling it. (It requires Admin rights, of course. ) It is not recommended as you do a very effective job or nutering the Vista Security Model by doing so.
If it, of course, your choice. we IT Admins have a lot more issues with this than the standard user, but for me, I gladly take the tradeoff because I worry a lot less about those few I HAVE to give Admin rights to.
Good luck! -
O.S. / Hard Drive Size for NIO Server/Client's load testing...
Hi All
I am currently load testing a NIO Server/Client's to see what would be the maximum number of connections that could reached, using the following PC: P4, 3GHz, 1GB RAM, Windows XP, SP2, 110 GB Hard Drive.
However, I would like to test the Server/Client performance on different OS's:
Which would be the best possible option from the following:
1. Partition my current drive, (using e.g. Partition Magic), to e.g.
- Win XP: 90 GB
- Win Server 2000: 10 GB
- Linux: 5 GB
- Shared/Data: 5 GB
2. Install a separate Hard drive with the different hard drives
3. Use a disk caddie, to swap in/out test hard drives.
4. Any thing else?
- Would the Operating System's hard drive size affect the Server/Client's performance, e.g. affecting the number of connections, number of File Handles, the virtual memory, etc.?
Many Thanks,
MattYou can use a partition on the same HDD or use a second HDD, disk caddie well if its a direct IDE or SCSI. If its usb no it will be too slow, may be if you have a fire-wire but I still don't recommend it.
Be careful if you don't have any experience installing Linux you may do multiple partitions on you disk without knowing, because Linux ext partitions are not visible to windows.
Recommended disk size for fedora is 10 GB. This is the amount of data that will be created on you HDD when you do a full installation. -
Non-blocking Server/Client is blocking...?!
First, a simple question:
Why in most example code using Selectors, when iterating over the Set returned by Selector.selectedKeys() does the currently selected SelectionKey get removed from the Iterator? I see it all the time, but since the SelectionKey is still bound to the underlying Selector it seems to not really do anything.
Now to my main problem:
I been working with 1.4 for a week now trying to implement a simple test server/client, whereby the server constantly sends out the current time to any subscribing clients, who in turn display the time to stdout. Pretty straight forward, huh?
Well, everything seems to go fine...once. The Server accepts the client connection, sends out a the current time, the client (only one for now) receives it, displays to the screen, but then both server and client block on the Selector.select() method.
If I shut down the client, the server then continues through the select() method, finding one SelectionKey, tries to write to it and throws an IOException (since the client is no more). I'm catching that exception and then removing the channel from the Selector, so that the server may continue to service requests.
When starting a second client while the first is still running causes the following sequence of events:
Server: starts up
ClientA: connects to server
Server: broadcasts the time
ClientA: displays time
// nothing else happens until...
ClientB: connects to server
Server: broadcasts the time
ClientA: displays time
ClientB: displays time
//everything blocks again...
ClientA: disconnects from server
Server: broadcasts the time
ClientB: displays time
As you can see it seems everything blocks until a client does something (connect/disconnect).
I will post code if anyone asks, but I don't want to spam the board if no one is willing to help me.

Printing a hashtable to screen, Server & Client (Java & CORBA)
Hi all,
I have written a server method that prints a hashtable's contents to screen:
public void viewAllEquipment () throws noEquipmentInTable {
// Does any equipment exist?
if (equipmentList.isEmpty() == true) {
throw new noEquipmentInTable();
System.out.println("The equipment list is as follows: ");
Enumeration tableEntries = equipmentList.keys();
int i = 1;
while (tableEntries.hasMoreElements()) {
String names = (String) tableEntries.nextElement();
System.out.print(i + ". Name = " + names + ", Description = " + equipmentList.get(names));
i++;
}The Client uses simple code to call this method:
hireCompanyServant.viewAllEquipment();As I'm sure you're probably aware, the Hashtable's contents gets printed to the Server screen not the Client screen! How can I get it printing on the Client instead? I'm unsure whether returning a value via the method would work, and can't think of any other way to do this.
Any help would be greatly appreciated.
Thanks
Edited by: JonBetts2004 on Mar 7, 2008 5:14 AMHaha, ok sorry, will do. It's all command-line based, CORBA client-sever model.
Client: A file/program that implements and calls methods given by the Server.
Server: A file/program that contains methods that can be called by other clients/servers.
Screen: command line interface.
As it is a CORBA implementation, an ORB is started, then the Java Server is started, and finally the Java Client is run in the command prompt, which shows a list of actions to take (add equipment, edit equipment, view equipment, etc).
Sorry if that's too vague, I find these things hard to explain.
But basically, the 'client' makes use of the viewAllEquipment method provided by the 'server', which prints the contents of a hashtable to the command line. It is printed to the Server's command line rather than the Client's. I need it printing to the Client's command line, but am unsure what is the best way to approach it. Changing the method from a void to a string, and then returning a value? Or something else?

Problem connecting to lotus notes server.
Hey Everyone
I am using:
Windows XP, service pack 2
PC suite 6.85.14.1
Bluetooth connection
Phone Nokia E65
I am trying to connect my laptop to the office lotus notes server. But it seems PC sync can’t locate my id file or the notes server. The fields under sync setup are simply empty.
My Notes client didn’t have any problems connecting to the server.
There are about 10 other people in the office all using the same setup (Nokia E65 and a the same type laptop) without problems.
I have tried the solution in this topic but it didn’t help: /discussions/board/message?board.id=pcsuite&message.id=24092&query.id=149864#M24092.
Any idea what the problem might be?
Thx in advance
\Andreasopen regedit
go to HKEY_CURRENT_USER\Software\Nokia\PCSync\Settings
open => NotesIni
instead of for exemple => C:\Application_Data\notes\
type the entire path => C:\Application_Data\notes\Notes.ini
it should work -
Uncaught exception raised in Server Client-side plugin
When I try to connect to my XServe from the Server Admin on my desktop computer. I get the following error:
Uncaught exception raised in Server Client-side plugin
Sorry but the feature you tried to access cannot be used. Exception is:
In updateConfigurationViewFromDescription: NSInvalidArgumentException * -[NSCFNumber count]: unrecognized selector sent to instance 0x18819ee0 .
There is a second error with similar wording.
If I say ok to the warnings I can make changes but they do not save.
I can access the Server Admin on the XServe
Anyone know of a solution so that I can login and edit the settings for my XServe from a remote computer?I'm getting this too, server is XServe running 10.6.6, remote Server Admin is on a 10.5.8 PPC iMac. No errors with same remote against a PowerMac server running 10.5.8. No errors with 10.6.6 remote against either server.
Unlike the OP, however, the changes I've tried "take." The pop-ups are annoying though.
Another issue with the 10.5 Server Admin/10.6 Server, if it isn't a thread hijack, disk volumes do not show up in the File Sharing pane, Share Points appear OK. -
Leopard Software Update Server + Client
Hello,
Now I have to use Mac OS X Tiger Server Software Update Server and OSX Tiger Client.
After installing OS X Tiger Server software update, I turned on the server and on apdaty do I download and have been prepared. OS X Tiger has found his client software update server, and everything worked.
Now I have OS X Leopard and Leopard Server Client.
Purely installed server and client purely installed. The server is running the server software update is downloaded updates. Leopard Client still download updates from the Internet and not from the local network and I do not know where the error. Why in the older version of all work without interference with the terminal and not now? Can someone please help me set the software update server to the client computers may not have anything set up and found this site automatically.
Thank you
I apologize for my incorrect EnglishThe Tiger systems must have some form of customization. SWU is not an auto-discover service. If you have one of the Tiger systems still available, enter both of these commands and report the results:
defaults read /Library/Preferences/com.apple.SoftwareUpdate
defaults read /Users/<adminusername>/Library/Preferences/com.apple.SoftwareUpdate
Does either of the results return the custom CatalogURL value? If not, then look in NetInfo Manager and look at your MCX values. There may have been a managed preference set for all systems. However, if Tiger systems are not bound that this is not possible unless an niutil command was run to insert the value.
Also, keep in mind that if your Leopard systems are not bound to OD, and you have Apple Remote Desktop, you can use a Send Unix command and hit all of your systems in a matter of seconds. It is really rather trivial.
Also, were your Tiger machines imaged from a DMG or a NetInstall Server? It is possible that the SWU custom address was set in the master image. This is why it appears to "just work." -

How to check Integration Server Client and ABAP stack Client?
How to check Integration Server Client and ABAP stack Client? How to check,,pls tell in detailed steps???
Points would be awarded.
Arnabhi,
Must be the server has different clients,one declared as application server ie abap stack client and the other declared as Integration server ie XI. U might be trying to open idx5 in application server client, in which idx5 exists but you cant open the screen even, that can be achieved through we02.
000 is the default client when XI server is installed .We can create separate clients on the system through sccl tcode.
As told we can find the client on sap logon screen.
Logon to sxmb_adm and check whether the client is declared as an application system(r/3) or Integration server(xi).Try idx5 in xi not r/3
