Change hostname on Cisco devices that are in production
I'm new to Cisco devices and to my current job as network analyst. Mostly in an attempt to establish consistency and to ease identification, I'd like to change the hostname of most of our Cisco switches and routers. However, I don't want to create any other problems.
If I proceed with the hostname change on our Cisco devices that are in production, would there be any negative impact that I may expect?
Thanks in advance!
Hi
Couple of things spring to mind
1) DNS resolution. How do you resolve the hostnames for your routers/switches now ?. if you do it via DNS then you need to update it to reflect the new name.
2) Any scripts etc. that you may use to automate taks on your network may need updating although if they use DNS to resolev just see 1
3) SSH. If you are using SSH to manage your routers/switches and you change the hostname the ssh key will become invalid. You will need to regenerate the key.

Managing Cisco Devices That Are Often Offline
In my environment, there are remote network devices that are turned on/off on an as-needed basis. Since we can't know when they'll be on the network, they cause failure alerts in Ciscoworks ( say RME tried to inventory them while they are offline ). Is there a best practice for handling this case? My idea is to create a user group of devices that are excluded from schedule inventory/configuration backups so that we can prevent the alerts.from being generated. However, I don't know if CiscoWorks has this capability .

I'm wondering how people are migrating their embedded devices that are using the FBWF. I've done some googling and it seems like most people are just re-imaging the devices and after migrating a single device i see why. Its not a pretty process. This will
be a long description but ultimately my question stems more from trying to find a better way to execute the device migration from 2007 to 2012.
Some back ground on my situation might be in order here. I'm in the process of wrapping up our 2007 to 2012 migration. We have a 2007 infrastructure that was a central server with 2 primaries and 286 secondary site servers. I've consolidated that to a single
2012 primary site server that hosts all the main roles. There are 2 more servers in the data centers both operating solely as push distribution points I'll refer to them as 2012 01 02 and 03. I'm over half way through the migration and so far haven't needed
to offload any site roles. There are almost 10,000 clients now reporting to the 2012 site server and almost a 100 field servers pulling content from 2012 02 as their source dp as pull dp is the only way forward for this many devices. I've read the horror stories
of trying spin up 200 plus push dps. We are running PKI. I'm at the point now where i need to start migrating the Windows Embedded Seven Standard clients that have the 2007 sccm client on them with WEDM for write filter handling.
What i'm wondering is if anyone has any pointers for me regarding migrating the WES 7 devices. My plan that i've come up with is to somehow script the process using a 2007 WEDM Task Sequence to try and migrate them over to 2012. Things are complicated as
I need to somehow script the install, the policy checkin, hardware inventory, software inventory, and validate the SCEP client installs before I reboot the device one last time to enable the FBWF. How I handled the SCCM 2007 client install on these devices
when they were provisioned was to just create a batch file that would sleep for ten minutes then check to see if the inventoryagent.log file had been created yet. I realize now that is inefficient as i can kick off the inventory using a WMI method once the
client has installed. Also I need to make sure the machine gets its first policy as that is how it creates the communication using PKI through that first policy transfer and that also finalizes the client install. The biggest piece i'm uncertain about in this
regard is the SCEP client.
I had to change the SCEP client install from yes to no in the default client settings as we have some Mcaffee servers that can't have the SCEP client on them. I have incremental updates enabled on the collection that has the policy that installs the SCEP
client but this will take an unknown amount of time unless i force the environment to update as the device starts in 2012 install, or if I could kick off the SCEP isntall... IDK. I'm also wondering if i should keep the device in the migration process until
i validate it has its proper scep policy applied which I believe can be validated by a registry key somewhere.
Once the 2012 client gets installed will that cause it to lose its place within the 2007 Task Sequence? Considering its going to take a minimum of 2 reboots I'd normally use the task sequence to handle its progression through the process.
I'm also considering trying to use an Orchestrator runbook, as that would be a good way to keep track of the migration process as each device migrates. Especially since this might take several seperate scripts.
I'm going to take a stab at scripting the migration process, but if anyone has any pointers that might make this a less complicated I'd really appreciate it as I've got about 3000 of these devices that need to be migrated over. The other things i've learned
the hard way is any time you have something this complicated over the course of 3000 devices you will run into unknowns and the failure rate increases. I'm in the precarious position of having to not only build this process out but in some situations have
it complete in the shortest amount of time possible as we have sites running 24x7. I know the end users behavior all to well and they will just keep hitting the power button sometimes even though their not supposed to so they can get their device functional
again. In those situations i'd end up, if i'm lucky with a device that no longer has a healthy SCCM client in either environment and the write filter disabled.
So like i said any pointers anyone could throw my way i'd really appreciate. I manually went through the migration process on a single device for proof of concept and ended up with almost 2 pages of pseudo code for my migration script/scripts.
Thanks,
-K.R.Hi,
In R2 there are some new variables you can use to solve this,
http://ccmexec.com/2014/12/smstsmplistrequesttimeout-value-in-milliseconds/
In Sp1 though adding a step to sleep for 2-5 minuter after reboot and before the application install step is a common workaround.. a powershell command with "Start-Sleep
-s 120" should do it.

Last known fix for Find my iPad? How is this not an included option for devices that are currently turned off. Absolute no brainer. Thief steals the iPad and turns it offline, or user loses it while it has low battery, lost forever. Brilliant.
If the iPad was running iOS 7, the thief/finder will not ever be able to use it.

Windows 7 x64 only installs the drivers for USB devices that are plugged in upon system startup
Hi all,
I have a most unusual problem. On my personal desktop, I can only use USB devices that are plugged in upon system startup. If I unplug a USB device and then plug it in again, the driver will not install correctly. I cannot force the device to start and I
can't pick a driver manually. All I get is this. If I plug in a USB device and then reboot, the driver gets installed correctly and I can use it until I unplug it again. I'm pretty sure it's a Windows issue
but I can list the hardware I have if it is needed.
I have tried:
Running an SFC /SCANNOW as administrator
Uninstalling all USB controllers via device manager and letting them reinstall
Neither worked to resolve the issue. If this was a client's computer I would probably just reinstall Windows but because this is my main work PC it'd be a huge hassle to do it, so I'd really appreciate any other ideas anyone has. If I have to reinstall I
will. Thanks!Hi,
Since the issue just happened for 4 monthes, I consider that some changes or updates may cause the issue.
Please also try to restore the system back to the point before this issue.
You can also try these steps:
1.Power down your laptop or desktop
2.Physically unplug the computer. If it’s a laptop, remove the battery too.
3.Leave it disconnected for three minutes
4.Replug the desktop or reinsert the battery
5.Power on the system
For the reasons, you can refer to this article:

I have recently recieved messages indicating that my start up disc is almost full. Consequently I need to remove some files from my hard drive. I've backed up my hard drive onto a NAS system & onto an external harddrive. The problem now, is that whenever I try to delete a file, a message comes up saying that if I remove this file from my hard disc it will remove it from all my other devices that are syn. to it. How do I remove a file (movies) from my iMac but not from other devices.
Thanks for your help
RobertYou're right - this question has nothing to do with iSync!
You're best bet would be to buy yourself an external Firewire or USB 2.0 hard-disk. There's no way you'll get 150gb onto an 80gb drive - certainly not in an instantly accessible way.
Your new Mac would've had the Migration Assistant appear during the initial OS install. This allows you to connect your new and old Mac together via a Firewire cable and automatically transfer your important files from old Mac to new.
Once you've all the files off your old Mac, re-format it and re-install the OS that came with it. If you boot up the Mac from the OS install DVD, there is an option to re-format the HD and install the OS.

My iMac holds my main iTunes account and it shows 4 devices are authorized to play iTunes. I can only name 3. How do I find out a list of all the devices that are authorized from this computer?
I don't believe this is possible, but you can deauthorize all your computers and start over if you are concerned.

ICloud has loaded my contacts to my daughters iPhone how can I separate 2 devices that are on one account
You can't. The whole point of iCloud is to sync contacts, calendars etc to all devices connected to the same account.
For your daughter to maintain her own contacts and calendars in iCloud, she'll need her own iCloud account, using her own AppleID. Sign out of iCloud on your daughters phone then setup a new iCloud account for her:
http://www.apple.com/icloud/setup/ios.html
(Note that this does not affect purchases made from the iTunes / AppStores. You can still use different AppleIDs for both iTunes and iCloud on the same device.) -

I have received notification that the "Complete My Album", Music Speaks by Candice Glover is now available to download. I have three devices that are all enabled to receive automatic downloads. My problem is the same on all three devices.
Only 0.05 minutes download on each song with the exception of the original song purchase: I Am Beautiful. What needs to be done to solve this problem?It seems that I have solved my issue by performing a full factory reset (erasing all content, something which I had hoped to avoid) restoring from an iCloud backup did not alleviate the issue, I had to set up as a new iPad.
Hopefully anyone else else who has this issue in the future will be able to find this. -

When I use the HP printer scanner diagnostic shows 2 devices that are no on my network.
When I use the HP printer scanner diagnostic shows 2 devices that are no on my network. The program cannot communicate with them (duuh! But they show up every time I run the diag program. How does the program even find them? Is there something in my registry? Thisis NOT at all a killer, just a PITA. Any suggestions are appreciated.
Thanks
John SchroederThanks for the response. I am going to take the "If it ain't broke ..." path Not worth the effort to track it down.
But, if someone from HP wants to pipe in and say where they get the list of printers in the diagnostic, I am all ears - just curious! And, maybe they will add a feature to delete these spurious "printers" in a future release of the diagnistic.
Thanks Again!
