Network outage don't bring down layer3 isdn

Hi Everyone,
Just wondering if someone ran through this case over the years...
Scenario :
2 routers in mgcp with 1 T1 on each. The DMS switch cascade the calls to the second T1 if the first one fail.
In a case you lose network connectivity on the first router, thus having the mgcp in a down state the calls should go to the second T1 but having mgcp down doesn't bring down the layer3 on the isdn link... I still ses the isdn status as MULTIFRAME ESTABLISHED...
I tried the busyout command but this only put channels in a busy state ... the first T1 still receive the incomming calls thus not cascading...
Anyone have an idea of what I could do to make the isdn link go down when the mgcp go dwon as well ?

Look into busy-out monitor feature:

Does adding 100Mbps Switch bring down the speed of a 1000Mbps network?

I have a wired Airport Extreme network where a 1000Mbps Ethernet switch in one room adds connections to other peripherals.
Now I want to add a switch in a different room for wired connections that are now operating wirelessly. And I have available a 10/100Mbps Ethernet switch. If I add that to the network do I bring down the speed of the entire thing? I realize that the connections directly from that 2nd switch can only be 100Mbps.
But will I affect the speed of the other connections?
Thanks in advance.

Correct

My MBP is bringing down network connections

When I connect my MBP either by ethernet cable or wireless I eventually bring down the network. I've connected to different networks with different routers and I always get the same result. After a brief period of time I lose my internet conncetion and I can't even communicate with the router. The router needs to be reset in many cases before it recovers. I have posted this issue before and the response was that it really couldn't be the Mac. However, once I tried connecting to other networks and got the same results I became certain that it is due to my computer. Is there anyway that I could be sending some corrupt packet? Hardware is failing? Is there a way to nuke all network settings and have it start from scratch w/o putting on a fresh install?

I found a solution that seems to work for the linksys WRT54GS v.6 router. Apparently many others have had the same issues with this brand. Under router settings I disabled UPnP and limited the MTU to 1480. Everything seems to work so far, knock on wood.

Prepare Exchange 2010 for a Major Network Outage

We are planning to replace our Core networking switch in our production environment. I am looking for a best practice option for Exchange to be placed into during this outage. This will be an approximate four hour outage.
Our current environment for Exchange is this:
Exchange 2010 SP3 rollup 8v2 two CAS servers and Three MBX/HT servers.
I read a few articles and they recommended different things, one was to just power down all of the exchange servers before the outage and then bring them back up after the outage. To me this just seems like a bad idea. The other was to put the MBX servers
into maintenance mode prior to shutting them down. This seemed more practical.
Can anyone provide feedback, insight, and guidance in this case? Has anyone gone through this type of outage and if so how did you handle your exchange environment and what was your success or failures with the scenario you used?
Thank you

When the server is in maintenance mode it moves all the active databases to other DAG members. It pauses the node in the cluster, and sets the DatabaseCopyAutoActivationPolicy mailbox server setting to Blocked. The Suspend-MailboxDatabaseCopy cmdlet is run
for each database hosted by the DAG member, and the cluster core resources will be moved to another server in the DAG if needed. This prevents data bases from auto activating in the case of a server failure. Just powering down an exchange MBX server would
cause the active data bases to failover to the alternate server, but once Quorum is lost due to more than half of the servers being shut down, I am not sure how the data bases would react after being brought back on line. Based on
this it seems to me that putting the servers in maintenance mode prior to powering them down would be the safest bet.
TL;DR What I am really looking for is advice or experience from an Admin who has already gone through a similar exercise.
Thanks for your input.

Time Capsule bringing down my internet modem.

Time Capsule bringing down my internet modem.
I have been having issues for several weeks where my internet modem loses its connection (often the Time Capsule wireless network would continue but without its connection to the internet since my cable modem was down). I replaced my cable model with Time Warner but the problem continued where I would routinely lose the internet and have to unplug the modem and router several times to get it working again.
I tried removing the router from the equation and connected my laptop directly to the router via Ethernet cable. This seemed to work and the internet modem no longer dropped the connection. It seems the problem is some combination of the internet modem and time capsule router, though I have been using the same Time Capsule router for over a year with no issue.
I used Airport Utility to restore the factory settings on my Time Capsule and reconfigure the network from scratch. Once again the wireless and modem seemed to work together for an hour or so and then the modem dropped the internet again.
I can keep unplugging the modem and router every time this happens but there must be something causing a conflict somewhere. Any suggestions of things I may try to fix or diagnose the issue between the modem and the router?

Is the cable modem you have also a router?
If it is a pure modem I don't really see how a TC can pull it down.
Can you get any access to the TC in the state when there is no internet? Can you check if the WAN still has IP address via utility.
You need to use the v5 utility btw to get any useful troubleshooting info. For Lion just download and install it.
http://support.apple.com/kb/DL1482
Check the Log for any info there.. keep your eye on it if you cannot access the TC once it goes bad,, you need to try and get the info prior to failure.
How old is the TC? What model.. please the A1xxx model from the rubber mat.
If you have A1355 ie Gen3 there is a chance you are seeing the ethernet ports failing due to internal power supply problems.
I think a Gen4 is still too new to see this problem.

Network speed affected by large file copy operations. Also, why intermittent network outages?

Hi
I have a couple of issues on our company network.
The first is thate a single large file copy imapcts the entire network and dramatically reduces network speed and the second is that there are periodic outages where file open/close/save operations may appear to hang, and also where programs that rely on
network connectivity e.g. email, appear to hang. It is as though the PC loses it's connection to the network, but the status of the network icon does not change. For the second issue if we wait the program will respond but the wait period can be up to 1min.
The downside of this is that this affects Access databases on our server so that when an 'outage' occurs the Access client cannot recover and hangs permamnently.
We have a Windows Active Directory domain that comprises Windows 2003 R2 (soon to be decommissioned), Windows Server 2008 Standard and Windows Server 2012 R2 Standard domain controllers. There are two member servers: A file server running Windows 2008 Storage
Server and a remote access server (which also runs WSUS) running Windows Server 2012 Standard. The clients comprise about 35 Win7 PC's and 1 Vista PC.
When I copy or move a large file from the 2008 Storage Server to my Win7 client other staff experience massive slowdowns when accessing the network. Recently I was moving several files from the Storage Server to my local drive. The files comprised pairs
(e.g. folo76t5.pmm and folo76t5.pmi), one of which is less than 1MB and the other varies between 1.5 - 1.9GB. I was moving two files at a time so the total file size for each operation was just under 2GB.
While the file move operation was taking place a colleague was trying to open a 36k Excel file. After waiting 3mins he asked me for help. I did some tests and noticed that when I was not copying large files he could open the Excel file immediately. When
I started copying more data from the Storage Server to my local drive it took several minutes before his PC could open the Excel file.
I also noticed on my Win7 client that our email client (Pegasus Mail), which was the only application I had open at the time would hang when the move operation was started and it would take at least a minute for it to start responding.
Ordinarlily we work with many files
Anyone have any suggestions, please? This is something that is affecting all clients. I can't carry out file maintenance on large files during normal work hours if network speed is going to be so badly impacted.
I'm still working on the intermittent network outages (the second issue), but if anyone has any suggestions about what may be causing this I would be grateful if you could share them.
Thanks

What have you checked for resource usage during one of these copies of a large file?
At a minimum I would check Task Manager>Resource Monitor. In particular check the disk and network usage. Also, look at RAM and CPU while the copy is taking place.
What RAID level is there on the file server?
There are many possible areas that could be causing your problem(s). And it could be more than one thing. Start by checking these things. And go from there.
Hi, JohnB352
Thanks for the suggestions. I have monitored the server and can see that the memory is nearly maxed out with a lot of hard faults (varies between several hundred to several thousand), recorded during normal usage. The Disk and CPU seem normal.
I'm going to replace the RAM and double it up to 12GB.
Thanks! This may help with some other issues we are having. I'll post back after it has been done.
[Edit]
Forgot to mention: there are 6 drives in the server. 2 for the OS (Mirrored RAID 1) and 4 for the data (Striped RAID 5).

HT3576 I have many apps where i must swipe down and it constantly brings down the notification screen. Is there anyway to disable this or activate it a different way because this really bugs me.

I have many apps where i must swipe down and it constantly brings down the notification screen. Is there anyway to disable this or activate it a different way because this really bugs me.

I don't have that problem. Perhaps I touch the screen lower when I wipe down? I don't know for sure but there's got to be some difference in the way that we wipe down. you might wish to do some experimenting.

WLS -JDBC sql server 2005, if sql server down bringing down entire cluster

Hi ,
From 4 WLS we connect to 4 indivudual SQL Servers 2005 (non clustered) , if one sql server goes down it is bringing down the 4 WLS servers. Tried all the possible parameter tuning in WLS nothing helped.
Is there any solution, if there is one sql server down can we mark the bad sql server down and don't create STUCK threads to all 4 WLS.
Thanks
Manu

Hi Weinstein,
when one sql server went down we saw the SQL server SHUTDOWN in progress. We use the DRIVER weblogic.jdbc.sqlserver.SQLServerDriver. When one server is going down connection pool is keep going to the same server and creating stuck threads.

In .net they have Retry Wait and connection will not go to the failed server until certain time, do we have any parameters like this in weblogic connection pool.
http://support.microsoft.com/kb/169470
1.     Q. With ODBC 3.0 Service Pack 1, will the ODBC driver manager try to connect to the database server repeatedly when the server is not available?
A. ODBC 3.0 Service Pack 1 introduced a new API, ODBCSetTryWaitValue, to prevent the ODBC driver manager from connecting to an unavailable server repeatedly. ODBCSetTryWaitValue takes a DWORD parameter and saves the information in the registry at the following location:
HKEY_LOCAL_MACHINE\Software\Odbc\Odbcinst.ini \ODBC Connection Pooling\Retry Wait
Once the diver manager detects a bad database server, it returns an error message and marks the connection with the time. From that point until the RetryWait value expires, the driver manager returns a failure without trying to reconnect to the database server
Thanks for your help.

Network Outage !!

I live in the Finger Lakes Region in Upstate NYS. My Iphone has a complete network outage.. shows that I have signal and 3g data but will not call, text, or use any data applications. I have restarted, reset network preferences, and have done a hard reset, nothing has worked. I found out talking to people around the office that all of their phones are doing the same thing and we (30 people) have different phones. Checked with my friend who has AT&T and he has no interruption in service at all. Anyone else experiencing this? Is this just another crash from the "dependable" Verizon?

@anch368 Thank for posting. I find it regrettable that you are having service issues with your iPhone. Are you still experiencing the interruption? If so and since you’ve done the master reset please PM me your name and number and I can see what other options we have for you. I hope this helps. Thanks.

Common Mistakes done while Bringing up an Iap in cluster

Q: Common Mistakes done while Bringing up an Iap in cluster.
A: COMMON MISTAKES
•   Network issues
    o   IAP fails to get an ip address
    o   Master and local are part of a different subnet and firewall in between
   o   Multiple DHCP servers in subnet.
   o   Native VLAN of the trunk that an Ap is connected is a dummy VLAN or doesn’t have a DHCP server.
•   Slave fails to join due to Ap image mismatch
•   Slave has different regulatory domain
•   Slave has different OEM build than master
•   Auto join is disabled
•   The uplink of the preferred master in the cluster in unstable.
Here are some Useful Troubleshooting commands which will help
Show Election
Show summary
Show log System
Show Ap’s
Show cpu
Debug-master-beacon (this command works only from console)

This error is resolved after following the logs in C:\ATG\ATG10.1.1\CIM\log\cim.log. The root cause is I used http as protocol instead of t3 while specifying weblogic admin url.
http://localhost:7001 instead of t3://localhost:7001
Thanks.

B520 - how to bring down the monitor contrast?

Brightness control in the front panel are not enough.
the backlight is too much for me to handle
Does anyone know how to bring down the contrast even more?
thank you.

I'll clear this up a little...
NVIDIA Controls does not have any control over the lamp / backlight on the screen. You can turn down
the gamma / brightness / contrast, and you may think you see it darker.
YEEEEEEES. it's dark but the intensity of the backlight is still there. You can feel it from miles away.
I chose Lenovo over ASUS just because of the GT555 option, and it was the worst mistake ever.
Asus Et2700 series do have Contrast/Brightness controls for the screen in Values from 0-100.
You can turn the screen completely dark if you want. Asus have never let me down, but thanks to my greed
always wanting more, thought i would never feel complete unless i had the gt555.
This is what happens when you fall for the marketing agenda.
Fortunately, i sold it already. And this would be the last time i'll purchase something from lenovo.
I'd like to think this is something that they just never thought. WRONG!!!. They know. they do it on purpose.
That's their way to make you feel incomplete, so you can start chasing for something else and fall again
in the marketing agenda.
There's always a way to make an "ALMOST PERFECT" product, the worst nightmare for you.
they have done this for years, since the beginning of times.
Let's not forget about the SATA performance issue in H67/P67 chipsets:
http://www.pcstats.com/articleview.cfm?articleID=2589
the B520 is one of the lines affected and lenovo did nothing about it.
And please let's not forget about the Trojan that got infiltrated in the drivers disc
for the B Series Line.
Hopefully, your campany will get a FORMAT C: by the end of this year.
arrivederci.

I performed a software update and the system is installing an update but it has been running for over 24hrs and keeps saying "This may take a few minutes, don't shut down your computer" Can anyone help?

I performed a software update and the system is installing an update but it has been running for over 24hrs and keeps saying "This may take a few minutes, don't shut down your computer" Can anyone help?

Hello cor-el, thanks for your reply. I changed my settings for downloads to desktop and it has appeared on there. When I double click I am asked which program I want to open file. I click firefox and another box "opening install" says I have chosen to open the file which is an application and do I want to save it. This is the only real option so I press save file. I get a box saying this is an executable file which may contain viruses - do you want to run. I press ok and the final box showing C drive file name and desktop appears stating application not found.
This happens the same whenever I try to install.
To my untrained eye the application is not being recognised as an application and I cannot work out how to get it to do that.
My plugin is still showing as out of date.
Is there anything you could suggest. Thanks for your time.

How to upload files in cluster without bringing down the cluster.

Hi,
Here is my problem:
My weblogic portal 7.0 application should run in 24x7 environment. The production
system is running in a cluster mode with external staging. Both the managed servers
are pointing to the same application sync database.
So to give a solution to this problem, we are trying to bring down one managed
server down and apply the patches into that managed server without bringing down
the other. Since webflow files and entitlements needs to be synchronized with
the portal database. If we perform a sync on the portal database, there might
be a chance that it might corrupt the existing portal database state. Our deployment
would not be complete unless we perform a sync on the other managed servers. So
we could not able to update the latest pathces into the cluster without bringing
down the cluster.
What I would like to know is "Is there any work around to get rid of this problem?".
I would be delighted if any one provides the solution.
Thanks & Regards,
Ratnakar

Hi Ratnakar,
When you perform sync you do it against the admin server which in turn does it
to the managed server. If you want to apply any changes to webflow you can do
it on the live system itself. I mean apply the new webflow and entitlements and
do the sync on the live system. Also while doing sync there are two modes. One
mode will sync only the modified changes and the other will apply all of it. You
can opt for the first option by which you can sync only the modified changes.
This may bring a small disturbance but it will be unnoticed.
The other option is to have two separate domains(each having one admin & one or
more managed servers) which may be having two separate portal databases. In this
way you can apply patches to one domain while other domain may provide the service.
Regards
Shaan

Pls its very urgent - i dropped by iphone 3G and the display became very dim soon after and it still remains the same - pls advise what should be done to bring the display back to normal

Pls its very urgent - i dropped by iphone 3G and the display became very dim soon after and it still remains the same - pls advise what should be done to bring the display back to normal

sounds like you broke the display when you dropped it. There's nothing we users here can do for you.
Since the iPhone warranty does not cover accidental damage, you will have to pay to have your phone repaired or replaced. You can bring it into Apple for an out of warranty exchange in the country of purchase, or you can find a 3rd party iPhone repair store in your area.

Database Replication never fall back over MAPI Network in case of dedicate network outage

Hi All,
Exchange 2010 SP3 RU4 and every time I have an outage on dedicated network the replication stop working and all Database looses sync (content Index) and I have to manually resync all as suggested on
http://exchangeserverpro.com/cannot-activate-database-copy-content-index-catalog-files-in-failed-state/
Should be MAPI network used to replicate and sync (even if replication disabled) in case of dedicate network outage ?
I'm reading everywhere "Yes, Database copy will revert on MAPI network in case of dedicated network's outge, even if Replication is disabled on MAPI network" but it's not my case.
Everything else up and running fine but I'd like to avoid to resync manually hundreds of DB.
Any suggestion greatly appreciated.
Red.

Hi Andy,
I know the theory but replication and seeding NEVER revert on my working MAPI network
"In the event of a failure affecting the Replication network, if the MAPI network is unaffected by the
failure, log shipping and seeding operations will revert to use the MAPI network, even if the MAPI network has it's ReplicationEnabled property
set to False."
This is NOT true in my environment (Ex 2010 SP3 RU4)
Red.
Well, in your case just the indexing is failing yes when this happens? Or is all replication failing?
