Windows Xp machines cannot connect to Windows Server 2008r2 after Update from Microsoft.

After allowing sever updates from Microsoft, My customers XP Machines can no longer connect to the Windows server shares using the server name. We get "can't find path error". I can ping the IP address but not the Net-bios name. I
can connect by ip address but have a software that must use the name "server" in an executable. The workgroup sees all of the other computers just not the server, the server see's the windows 7 machines but not the XP machines. I have
tried every fix I can find in the forums and online. I did find and AD and DNS errors during the update. Errors 4004, 4005, 4015. Things I have tried: ipconfig flushdns, renew, registerdns, nbtstat -A servername, etc.
Thanks

As IP address works but not NetBIOS name, it seems like a DNS or WINS server related issue as Milos said.
If there is no WINS server configged, check DNS settings (server side) and suffix settings (client side).
Which system is updated, Windows XP or Windows 2008 R2? You can check the recently installed updates and provide us a list about all updates just installed.

Only *Security Updates* have MSRC Security Bulletin numbers, but not all security updates have MSRC Security Bulletins associated with them. In fact, there are a large number of security updates that are not associated with security bulletins. -242- of 'em
on my WSUS server.
Otherwise, the MSRC Number field will always be blank on non-security updates, and may be blank on security updates.

SAP ECC6.0 cannot connect to SQL Server Database after recreating DB server

We had a disaster with our ECC 6.0 Development system a few days ago. The system is called “DEV”. The SQL Server database server got wiped out and we didn’t have a backup. Luckily, we did have a backup of the database. Our system engineers rebuilt the server and our DBA reinstalled SQL Server and restored the database. The database came up fine, but when we try to start SAP, it fails. “R3trans –d” also fails. The database is SQL Server 2008R2 10.50.2769. The OS is Windows Server 2008R2.
We verified that the “devadm” and “SAPServiceDEV” accounts have permissions on the on the server. We set the following Environment Variables for the devadm account on the database server:
DBMS_TYPE = mss
MSSQL_DBNAME = DEV
MSSQL_SCHEMA = dev
MSSQL_SERVER = <database server name>
SAPLOCALHOST = <database server name>
SAPSYSTEMNAME = DEV
We also set the following Registry Key:
HKEY_LOCAL_MACHINE/Software/SAP/DEV
Type:     REG_SZ
Value:   AdmUser
String:   <database server name>\devadm
We didn’t install any kind of SAP software on the database server.
Is there any kind of SAP components we need to install on the database server? Do we need to run the SAP installer on the database server to get everything setup correctly? I looked at another one of our SQL Server database servers and it has SAP Management Console installed and there is a C:\Program Files\SAP\hostcntl folder. I don't know what that is or it has anything to do with SAP being able to connect to the database.
Here is the error message in the R3trans log file:

Connect to remote server broke after update to 10.5.5

After updating my system to Leopard 10.5.5, I can no longer access a critical server at work while at home. I get the Errror -36 message after a bit of a wait. I don't even get the login dialog.
I have tried both using the URL and the IP number to the remote server, with and without the "afp://"-prefix. (AppleTalk is enabled in the SysPrefs.)
I have also tried a 10.5.4-related tip that you could via Terminal alter the way the Mac sends its access codes. No luck with that either.
The server runs OSX Server (10.4.?) as far as I know. It used to work in 10.5.4. Any ideas?

If you are at home what are you doing to access the server?
I have tried both using the URL and the IP number to the remote server, with and without the "afp://"-prefix. (AppleTalk is enabled in the SysPrefs.)
If this is a critical server then it is unwise to have the afp protocol opened up to the internet. Also Appletalk is not used in Leopard for file sharing it is a legacy protocol that still exists for printers.
The server runs OSX Server (10.4.?) as far as I know. It used to work in 10.5.4. Any ideas?
If your server is running Tiger server you should enable the vpn server and use that to access it from outside.
If a server admin setup your Tiger server I would be very surprised if they had opened up AFP to the world.

IPad 2 cannot connect to Wifi before and after updating PLEASE HELP

i have been using iOS 5.1.1 till today.. the connection to wifi stopped working.. it slowly faded away and today i woke up and could not connect to My wifi at all, i have decided to update my iPad to iOS 7.0.4 but the problem is there
what should i doo ??

It could be a problem with your WiFi router or your iPad.
If you are having WiFi problems it is necessary to isolate whether the problem is with your network or your iPad. Note: Do NOT consider your network to be blameless if some other devices can connect to it.
First, test your iPad on some other WiFi networks: a friends, Starbucks, Barnes & Noble, etc.
If it works well there then the problem is probably with your network. Try restarting your WiFi router by removing power for 30 seconds. If that does not help check for a firmware update for your router. If none exists which corrects the problem consider replacing the router.
If your iPad does not function well on other networks it possibly has a hardware problem. You could try Settings > General > Reset > Reset Network Settings to see if that corrects the problem. If not, contact Apple Support or visit an Apple store for evaluation. They can provide a replacement if your iPad is bad.
If you need more help please give the make, model, and version of your WiFi router and how you have it configured.

Why did the colors on my Mac Air go weird when I connected it to my projector after updating from SL to Mavericks?

4 days ago, I updated my iOS on my Mac Air from SL to Mavericks. I connected it up with my projector to check on a keynote presentation I was preparing. The colors on my Mac went a strange greenish hue and this was accurately mirrored through the projector onto the screen. I tried to adjust the color setting in Displays and played around with different resolutions in the vain hope that something would fix it, but nothing did. There were all these new customized color adjustments you could do which I had never seen before. I have a MBP that I hadn't (fortunately) updated and went I connected it to my projector (with which I have never had any issues with before with my two Macs), there was absolutely no problem so I know it is very definitely an issue with Mavericks. In the end, in desperation as I do a lot of presentations and I can't afford to have this happening, I erased my hard drive and restored SL from Time Machine which I had fortunately done a back up just before doing the update. I had read in some previous threads here that restoring to a previous iOS is a long and complicated process but it was fortunately not the case for me - my Time Machine did it painlessly for me. My question is - I am now too afraid to try Mavericks again - but is there an explanation why this happened to my Mac Air?

Check Settings > General > Cellular > Cellular Data and make sure it's "On".

Cannot connect to Activation Server

My system is Windows Vista.
Recently installed ADE 3.0.
I tried to open ACSM file, both with & w/o authorization ID.
Both times, I get the same error: cannot connect to Activation Server
My internet connection works.
So, I configured my Windows Firewall, so that ADE 3.0 is on the exceptions list.
Same error: cannot connect to Activation Server
Help!

Yes, I tried to deauthorize in Library view, but nothing happened. ADE has no authorization information at all.
So, for added measure, I uninstalled & reinstalled ADE 3.0. Then I confirmed that Adobe ID and password worked by logging into my Adobe account. Hence, my internet connection also works.
In ADE I again entered my Adobe ID and password. Initially I got the same error: cannot connect to authorization server.
After I repeatedly hit [Try Again], the screen finally showed "Authorizing..."
However, this screen just runs...and runs. The authorization never completetes.
So then I went to the Registry and deleted the Adept Key, as you suggested in your other reply.
Same result. At first, it wouldn't connect to the server at all. Then I get the "Authorizing" screen that runs indefinitely.

The restor pocess did not succeed because your computer cannot connect to the server - Windows Server 2012 R2 Essentials Experience

Hi all
I've been running Windows Server 2012 R2 with the Essentials Experience in test for a Windows 8.1 client environment, on an HP ProLiant MicroServer N54L. Overall I've found the Essential Experience set-up over WHS2011 and WHSv1 okay; still looking to extract
any real value over the former versions.
This box has been up and running for a few months now, with client backups of a Win 8.1 box scheduled and running successfully every day. However when trying to conduct any file restores from the backups, to the client, I receive an error dialog once I go
through motions from the Dashboard:
On the 'Devices' tab, right-click the appropriate client and select 'Restore files or folders for the computer'
'Restore Files of Folders' dialog pops up, asking me to 'Choose a backup' from the list of all the backups that have run
Select any one in the list - have tried numerous backups; automatic, manual, etc. same result every time
Brings up the dialog to 'Choose a volume', choose either C: or D: partitions of the same fixed drive - again, no difference which one I choose, the outcome is the same
'Opening the volume' dialog starts, with progress bar, runs to about 4% complete the pops up the dialog 'The restore process did not succeed'. Full error in the dialog, "The restore process did not succeed because your computer cannot connect to the
server. Make sure that the computer is connected to the networkm and then try again
If my computer cannot connect to the server - how can I get that far? How can I open the dashboard, select a client, select from a list of backups, select a volume to restore, etc. What is going on here?

Hi,
Please check if a "host" entry for the server is added to the client. For more detailed information, please refer to the threads below:

Windows 7 64-bit connection to Oracle server 8.1.5.0.0
V8.1.5 is ancient, obsoleted & unsupported.
Combine that with Windows 7 & you have an Improvised Explosive Device waiting to explode in your face.

Deploytool cannot connect to linux server

HELP !!!
I'm trying to deploy an application from a Windows 2K machine onto a linux server on a small home network, but deploytool cannot connect to the server.
When I try File->AddServer it says 'cannot connect... please contact your server admin...' However, it works if i try to deploy locally on either machine.
I'm running a Samba network with static addresses on Redhat 7.1, and also with J2sdkee1.3 on both machines(Linux and Win2K). The machines on the network all ping each other successfully using both ip addresses and machine names.
I will greatly appreciately any help. Thanx in advance
Kawsu

I have the J2SDKEE-1.3.1 installed on a linux RedHat 6.2 machine as well as a Win2K machine. The deploy tool can connect to localhost on either machine but when I try to deploy across the network the deploytool appears to connect and then sit there and do nothing. If I then stop the server the deploytool will issue an error and remove the server from the server list. Based on this it appears to be connecting to the linux machine. Also I see no significant network traffic while it is sitting there.
If anyone has any information on this could you please reply to [email protected]
Thanks

System Update -- Cannot connect to proxy server - SOLVED

I'm on a ThinkPad T61 running Windows Vista. When I try to download from System Update, I always get the error message "Cannot connect to proxy server."
I have tried connecting to the Internet directly via Ethernet rather than through a wireless router--it doesn't make any difference.
I have also uninstalled System Update and then installed the version I downloaded from lenovo.com--same result.
System Update is an exception in Windows Firewall, and I have even tried running System Update with Firewall disabled--ditto.
Can someone please help me?
Message Edited by Tim_Lenovo on 01-29-2008 02:49 PM
Solved!
Go to Solution.

I have discovered one other potential cause of this behaviour.
If your computer is attached to a Domain, ensure you are connected to the Domain using a profile that has administrator rights when attempting these upgrades.
I was using a local profile with administrative rights, on a network connection that was outside of the corporate LAN, and I was getting the "Cannot connect to proxy server" error.
When I connected to our Corporate LAN and logged on to the machine with an administrative profile, the Proxy Server error went away, and I was then able to connect and download my required updates.
Just an FYI if you are doing this inside a large, firewalled LAN running from Active Directory.

Logon balancing error:cannot connect to message server (rc=9)

Hi Gurus,
I have just installed SAP GUI 710 in my new system and copied the saplogon.ini file to the respective folder in the new system.
I am now able to see the servers in the logon pad but not able to login .
When i try clicking the logon i am getting the below error message "
"Logon balancing error:cannot connect to message server (rc=9)"
Then further expanding the message i am getting the below message
" Error: Server '?' unknown
Tue Mar 02 11:51:05 2010
Release 710
Component NI (Network Interface), Version 39 rc =-3 , Detail NiErrSet. "
Can you please help me out in accessing the servers.
Regards
Vikram

Check OSS Note : 882741
Summary
Symptom
Some users cannot longer connect SAP GUI to any SAP systems e.g. via SAP Logon, SAPShortcut etc. although they have not made any update to either SAP GUI or SAP system. The attempt to connect to the SAP system ends with error messages like this: "Logon balancing error: could not connect to message server (rc=9)", "service sapmsXXX unknown" or "service sapdp## unknown".
The detailed error information is as follows:
    Error: service 'sap...' unknown
    Component NI (network interface), ...
    rc = -3, module ninti.c, line 463
    Detail NiPGetServByName: service 'sap...' not found
    System Call getservbyname

MSN Messenger 7.5,Connection Troubleshooter
Reason and Prerequisites
The reason for this malfunction is, that the datatype of the registry value HKLM\System\CurrentControlSet\Services\TCPIP\Parameters\DatabasePath
was changed from REG_EXPAND_SZ to REG_SZ.
The following programs are currently known to cause this registry change:
Starting MSN Messenger 7.5 "Connection Troubleshooter" (Build 7.5.0299).
Installation of MSN Messenger 7.0 or MSN Messenger 7.5 with the option automatic scanning and configuration of ports.
This modification prevents the expansion of environment variables in the value of the parameter. Therefore,
      %SystemRoot%\system32\drivers\etc
is not translated to
   c:\windows\system32\drivers\etc
and the services database is not found by the API function getservbyname().
If you have checked the datatype of registry value DatabasePath and it is REG_EXPAND_SZ, apply SAP Note 52959 to check the appropriate settings in the services file.
Solution
Start the registry editor and rename the registry value HKLM\System\CurrentControlSet\Services\TCPIP\Parameters\DatabasePath
Create an Expandable-String Value (REG_EXPAND_SZ) with the same name and value.
If more PCs are affected, you can export the correct value to a .reg file and import the .reg to other PCs.
If you have the same problem although you have not installed Microsoft MSN Messenger 7.5, create a customer message, collect the following information and attach it to the message according to note 541726 or upload it to sapservX (see note 40024):
Scan your workstations for spyware and viruses with up-to-date virus definitions. If you already did that what was the result ?
What software has been installed recently ? (client software, Firewall)
Create a registry export of the following key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstallon the affected and the unaffected PC respectively and attach the two .reg files to the customer message.
Are the users on the affected workstations logged on with administrative credentials (local administrator ) ?
Create an MPS Report Networking and Setup Perf of an affected workstation so that we can check if they use an software in common.
You can download the Networking MPS Reporting Tool at:
http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd915706/MPSRPT_Network.exe
You can find a short description about the features of the tool at:
http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd915706/MPSRPT_Network_Readme.txt
The Setup Perf MPS Reporting Tool is located at:
http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd915706/MPSRPT_SETUPPerf.EXE
Run this report too on identically configured workstations, which are not affected.
If you have already changed back the DatabasePath parameter and if after a while the value was switched back to REG_SZ perform the following steps to help us to identify the reason for this problem:
Switch the datatype back to REG_EXPAND_SZ
Download Regmon from http://www.sysinternals.com on the affected machines
Enable auditing on the affected clients
Modify the settings of the eventlog so that no important entry is deleted!
Open Regedit and highlight HKLM\System\CCS\Services\TCPIP\Parameters
Right-click on "Parameters" and choos "Permissions" and click "Advanced".
Choose "Auditing" and "Add".
Add "Everyone" and select "this key only" under "Apply onto".
Check the boxes "Set Value" and "Delete" and click "OK".
Apply these settings
Start Regmon and apply the correct filter settings:
Press the "magnifying glass" button to stop the monitoring.
Press the rubber button to delete all logged entries.
Go to "Options Filter/Highlight".
Copy the following value to the include field: tcpip\parameters\databasepath and click "Apply".
Start Regmon by pressing the magnifying glass button
Verify that logging starts when you double-click the TCPIP Key in regedit!
If the datatype will be changed again, provide us the output of the monitoring tools.
Solution provided by Microsoft
This issue is said to be fixed as of build 7.5.0311 of MSN messenger.

Windows Xp machines cannot connect to Windows Server 2008r2 after Update from Microsoft.
