Server Network Connection Loss with fast recovery.

Ok, so we are having an issue where our server is randomly losing network connection momentarily, but for long enough to boot everyone out. VMware seems to be related but we are having trouble understanding if VMware is just a symptom of something else happening or if VMware is indeed casuing this.
I was wondering if you guys might be able to offer your thoughts. At first we thought it was the MIC, and because we had a mirrored server we were able to swap to that and I think rule out that it's the NIC.
Thanks

If you're not current on your VMware software, patch that to current.
Please then consider asking the VMware folks directly. They'll be looking for details such as your version and the guest operating system. Also probably for the network configuration within the virtual machine; the details of the virtual network set-up.
In general, there's not a whole lot of VMware discussion traffic here in the OS X Server forum. There's also little or nothing on that stack that looks specific to OS X Server in that log. That is mostly VMware chatter, with some generic OS X networking for mDNS (Bonjour) traffic.
Put another way, this forum probably isn't the best spot to get an answer. The folks in a VMware forum will likely have a rather better idea of what those log messages really mean, and may well have seen this sequence before.

Does 'Network Connect' work with MacBook Pro?

My safari unexpectedly quits when attempting to log into my company's VPN.
- I log into our VPN website and the connection begins to initialize
- with my MacBook, Safari (2.0.3) unexpectedly quits
- with my PowerBook, 'Network Connect' automatically starts and the VPN connection completes without any problem
Does 'Network Connect' work with MacBook Pro? Any ideas?

Resolved. MacBook Pro was having trouble dowloading the 'Network Connect' application when I logged into my VPN client for the first time. I copied it from my PowerBook G4 over to the appropriate folder and it now works perfectly.

Local Network Connection Problem with SQL Server 2008 R2

Hi,
I have CRM application which uses SQL server 2008. Weird thing is that I have no problems connecting from client machines to the server when using a particular router (via LAN) and when I upgrade the firmware of the same router (A common open source firmware
which is used by many also works perfect apart from mentioned problem) and restart the server, the connection cannot be established. I get Error 40.
When i downgrade the firmware and restart the server, the connection works again.
Please note that I am absolutely not touching any configuration of the server. Also the CRM software allows remote connections from public IPs which this feature works fine with both downgraded and upgraded firmwares.
As for my understanding, the routers do not block ports in LAN connections. So how can I diagnose the reason for this connection problem?

Hi Leony83,
Please also help to check Windows Event Log information regarding this issue, so that we can do further investigation. In additin, here is the general steps to troubleshoot SQL Server Error 40 issue. Please see:
SQL SERVER – Fix : Error : 40 – could not open a connection to SQL server – Fix Connection Problems of SQL Server:

Windows 2008 R2 Driver for HP Laserjet 8150 - Network Connect Fails With 0x000004005 Error

Dear All,
I'm trying to connect to a network laserjet 8150 with Windows 2008 R2. The server keeps complaining that it can't access a suitable driver - even if I point it specifically to the universal printer drivers available on the HP web pages.
Connecting to the printer manually with a new TCP/IP port seems to work but I need to be able to use the 'right-click, connect' option as the printer is not using a standard port for normal use.
Any ideas anyone?
Many thanks.
Chris

Server refuses connection ONLY with one certain domain name AND from one hard drive

OK, this is kinda crazy and complicated, so bear with me and thank you for your interest. I have a Mac Pro with (3) Internal drives:
Boot is a SSD with all my apps and system software running 10.6.8. That's it.
Master has all my data files.
Mountain Lion has a clean 10.8 install, but I rarely use it.
I am a web developer and have a Wordpress site at www.timfleming.com
When I visit the site with Boot drive, it isn't loading the site correctly in any browser (Chrome, Safari, FF). It looks like no CSS is being applied and the image links are broken. I can get to my WP login page, but when I enter my credentials, the connection is refused by the server. Nor can I access the site via FTP in Filezilla.
If I visit with the Mountain Lion drive, no problem. Login no problem either.
Aha! You might say, there's some incompatibilty between your site and 10.6.8. Well, you would be wrong. I also have a MacBook Pro running 10.6.8 and the latest versions of Chrome, etc and have no problem connecting with it.
Even stranger, I have a local dev site, timfleming.com, that I cannot access with MAMP! Server refused connection
It's as if timfleming.com has been permanently banned from this machine!

You, or someone using your computer, may have modified the file /etc/hosts.
The easiest way to fix the hosts file is to restore it from a backup that predates the modification, or to copy the unmodified file from another Mac. If you can't do that, then do as below. Please read this whole message before doing anything.
Back up all data. This is a simple procedure, but if you don't follow the instructions exactly, you could be left with an unbootable system. In that case, you'll have to restore from a backup or reinstall OS X.
If you have more than one user account, you must be logged in as an administrator.
Triple-click anywhere in the line below to select it:
open -e /etc/hosts
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). A TextEdit window should open. At the top of the window, you should see this:
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1                              localhost

fe80::1%lo0                    localhost
Below that, you'll see some other lines. There should be nothing above the first line "##". If you have any doubt about that, STOP and ask for guidance. Make sure you scroll all the way to the bottom of the document. Scroll bars are hidden by default until you actually start scrolling, so you may not realize that you’re not seeing the whole document.
If the contents of the TextEdit window are as described, close it, then enter the following command in the Terminal window in the same way as before (by copy and paste):
sudo sed -i~ '11,$d' /etc/hosts
This time, you'll be prompted for your login password, which won't be displayed when you type it. If you don’t have a login password, you’ll need to set one before you can run the command. You may get a one-time warning to be careful. Confirm. Quit Terminal.
If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Log in as one and start over.
That will fix the hosts file. There is now a copy of the old hosts file with the name "hosts~" in the same folder as "hosts". You can delete the copy if you wish. Don't delete the file named "hosts".

SQL error forced rollback and connection loss with OLE item in forms 6i

We are running forms 6i client server on a Oracle Database 10g Enterprise Edition Release 10.1.0.3.0 - 64bit. We have a form that has 1 base table block that contains an OLE item where the user can create or edit a Microsoft Word document then save that document in a long raw column in the table. The OLE item is using the Word.Document.8 OLE class.
We are having intermittant problems where the user presses commit in the form and gets a FRM-40508 error: unable to Insert record. The message displayed at the bottom of the screen is FRM-40655: SQL error forced rollback: clear form and re-enter transaction. When I press Shift-F1 to view the error I see ORA-03113: end-of-file on communication channel.
DBA says that there are no errors being generated in the database. Does anyone have any experience with kind of problem? Any suggestions would be most welcome.

The Ora-3113 error means that the connection has been lost.
These issues normally are database or networking related and have little to do with ole objects.
You need to determine if a server-side error is causing the disconnect.
To start diagnosing this issue you first need to turn on sqlnet tracing to see what other ora-XXXX error is occuring. That will start to help diagnosing this issue.
You may also want to check the database alert log for any RDBMS errors that may have caused the disconnect.
If there aren't any RDBMS errors logged, you should generate a Net8 trace for the session to see if you can get more detailed errors.
About sql tracing:
To obtain a trace, you have to place the following entries in the SQLNet.ORA file. Make sure before you start your application that the C:\Trace directory exist.
TRACE_FILE_CLIENT = net817
TRACE_DIRECTORY_CLIENT = C:\trace
TRACE_UNIQUE_CLIENT = ON
TRACE_LEVEL_CLIENT = 16
TRACE_TIMESTAMP_CLIENT = ON
When finished obtaining both traces, set the TRACE_LEVEL_CLIENT = 0 from 16 to turn off tracing.

Network Drive problems with Fast User Switching

I have a USB drive connected to my Time Capsule and shared to the network. On one of my computers (Mac Pro) I have 2 user accounts which access the data (music, photos). The first one to access the drive after a power on has no problems, and everything works perfectly. However, if I Fast User Switch to the other account, it can see the drive but cannot access it (permission problem apparently). I then have to click the disconnect button in finder, and reconnect, and then can use it again fine. Then when I switch back to the first account its the same deal, having to disconnect and reconnect. It is really annoying, since it marks all my itunes songs as missing and whatnot. Does anyone know how to fix it?
Thanks!

Yes, under Sharing in System Preferences both users have been added to full access of the drive. I had to do that for the non-admin account to be able to access it at all.

Network connection fails with a "self assigned IP" or "no IP" msg displayed

I am having problems staying connected to the wireless network. I have four Macs - 3 MBPros and 1 iMac. They have all been upgraded to Snow Leopard and have had all recent updates from Apple.
One of the MBP, and just now the iMac, keeps disconnecting from the wireless network with a message that the IP address has been self assigned or that no IP address is found. These computers cannot connect right now but I am using another MBP and it is connected.
I've read through the forums and these are the solutions I have tried:
1. reset everything - the router, WAP, and the computers - this sometimes works and sometimes does not.
2. renewed my DHCP lease - at first this worked like a charm but now it makes no difference
All computers are using Airport Extreme
Router is Motorola, new last year
WAP is a Linksys Dual N band new last month (thinking that maybe the Netgear g was failing)
There are two PCs connected to the same WAP and they are (strangely) working fine.
How can I get these computers to just stay connected?

Since upgrading to Snow Leopard, I'm having the same type of problem and I have to reset my airport exterme because of NO I/P address. I would really like to find out what's up/ Until the Upgrade there wan NEVER a Problem - which is what I expect from MAC!

Trouble recognizing scanner when Officejet Pro is on network connection. iMac with OS X 10.8

I am considering replacing my Officejet Pro 8500 because the scanner is not recognized when the device on connected on the network. Printer is recognized and works fine, but scanner is not recognized from my iMac (OSX 10.8.2). I have the latest HP software driver installed.
However, the printer AND scanner work fine from another iMac (OSC 10.6) on the same network.
Is there a problem with the driver when running under OSX 10.8? Could it be that the driver is not installed correctly in the iMac running OSX 10.8 (I've installed the new driver twice). Could this be resolved by returning the 8500 printer (covered under 3rd party warranty) and buying an Officejet Pro 8600?
This question was solved.

AMacGuy ...
Thanks for the reply. The printer is the A910 version.
I am trying to scan from either the HP utility or from the Mac <system preferences> <Print & Scan> function.
When using the HP scan app, the scanner is not recognized. When using the Print/Scan function in System Preferences, the little window that comes up shows the HP Officejet Pro 8500 A910, but there is no Print/Scan tab at the top.
The printer works fine. The scanning funcction will not work (initiated from the Mac), whether connected by wireless or ethernet. When the printer is installed by USB cable, it works fine (print and scan functions).
Note: Connected on the network, if I access the printer by typing the local IP address in the web browser, both the print and scan functions work fine. Also, the print AND scan functions work fine from another iMac on the network - this iMac (my wife's) is running OS X 10.6, Snow Leopard.
I have talked to an Apple Care supervisor (very helpful), and we have uninstalled all HP drivers and apps, repaired disk permissions, removed all HP software using Disk Utility, then re-installed the HP driver pack from hp.com.
The problem seems to be due to OSX 10.8 and the drivers on the OSX 10.8 Mac when the printer is connected by network (wireless or ethernet).
Any ideas? I have been authorized by a 3rd party warranty service (through Office Depot) to return the printer for a refund (now almost 2 yrs old). Should I just return the printer and buy an Officejet 8600, or would this just have the same problem? I have also considered switching to an Epson WF 3540, just in case the problem is with HP's driver software.
Any ideas before I just return the printer to the warranty company?
Thanks.

Network connection loss/Computer lockups

Hi,
This is the setup i have:
Cable modem -> Airport Dual Band II -> Netgear gigabit switch which has multiple computers, VoIP phone, Apple TV and a 2nd Airport acting as a repeater.
My computer locks up or freezes randomly and I am trying to see where the issue can be, the netgear switch or the airport connected to the cable modem. Has any one experienced similar issues?
would it be better if I plugged the modem into the netgear and then plug everything else in to that switch instead?
Thanks in advance.

Welcome to the discussions!
Questions and a comment.
The 2nd Airport acting as a "repeater"...is this plugged into the Netgear ethernet switch, or is the device extending your network using wireless?
Is the 2nd Airport being used for wireless only? Which device is this?
+would it be better if I plugged the modem into the netgear and then plug everything else in to that switch instead+
No, that won't work. Your router must be the device connected to the modem with the switch coming after the router.

Ask another DNS server if connection fails with the current one

Hello,
I'd like to ask if there's an addon available or a hidden feature in Firefox which allows it to enable trying to use other DNS servers if a connection failed to a server. Lets do an example, would be the easiest way of explaining:
1. I want to connect to Google.com
2. Firefox / Windows asks the DNS server for the IP
3. Firefox tries to connect to Google but fails (Website took to long to answer for example)
4. Firefox will try another DNS server you have entered in your IPv4 DNS Page
Or does Firefox already do that? Because sometimes it fails to connect to a server while using a special DNS server. If I change the settings to another DNS Server it works.
Thank you

Please update to version 20.
