  • Which events specifically cause Windows 2008 to mark a SAN volume offline?

    - by Jeremy
    I am searching for specific criteria/events that will cause Windows 2008 to mark a SAN volume as offline in disk management, even though it is connected to that SAN volume via FC or iSCSI. Microsoft states that "A dynamic disk may become Offline if it is corrupted or intermittently unavailable. A dynamic disk may also become Offline if you attempt to import a foreign (dynamic) disk and the import fails. An error icon appears on the Offline disk. Only dynamic disks display the Missing or Offline status." I am specifically wondering if, on the SAN, changing the path to the disk (such as the disk being presented to the host via a different iSCSI target IQN or a different LUN #) would cause a volume to be offlined in disk management. Thanks! Edit: I have already found two reasons why a disk might be set offline, disk signature collisions and the SAN disk policy. Bounty would be awarded to someone who can find further documented reasons related to changes in the volume's path. Disk signature collisions: http://blogs.technet.com/b/markrussinovich/archive/2011/11/08/3463572.aspx SAN disk policy: http://jeffwouters.nl/index.php/2011/06/disk-offline-with-error-the-disk-is-offline-because-of-a-policy-set-by-an-administrator/

  • How can I create a windows shutdown script from powershell/command-line?

    - by David Rubin
    I've read the TechNet pages that describe using computer/user startup/shutdown scripts, and that's great, but I'd like to create those scripts via the command-line (and not have to click around in gpedit.msc). It looks like scripts.ini and psscripts.ini in %SYSTEMROOT%\System32\GroupPolicy\Machine\Scripts specifies the scripts to run, but those don't exist until running gpedit.msc for the first time. Is it safe to create and edit those directly? Or do I need to muck around with Set-GPO or something similar? Thanks!

  • Cannot schedule task to run under domain user account other than current user

    - by Filburt
    On our Win 2008 machines I can't schedule tasks for domain users because the domain name does not resolve to network name but the AD dc name. The "network name" looks like ABCDEFGE-HIJKLM and the "dc" / "name" would look like ABCDEFGE-HIJKLMN. When selecting the domain user account the account qualifier will look like ABCDEFGE-HIJKLMN\task.user. This results in an "invalid account" error. When however keeping the currently logged in user it will display ABCDEFGE-HIJKLM\current.user. Does this behaviour result from the presumable "illegal" domain name? Is there a workaround for this? update I could of course log in as the desired domain account and create the task but since this account is a account used for running services I want to avoid creating a user profile on the machine.

  • TFS 2010 and SCVMM to manage snapshots

    - by ELSheepO
    I have a VM with TFS 2010 and SCVMM 2008 installed on (I know your told not to do that). I have SCVMM linked to the host and thats working good, and have configured the scvmm on the lab management tab on TFS. My question is, how can you take/roll back snapshots automatically? ie install base take snapshot install patch run tests take snapshot go back to snapshot taken at step 2 Thanks in advance.

  • Considerations for spanned volumes with SAN's LUN.

    - by Patrick Pellegrino
    I want to know, before going forward, what I can expected in lost of performance (or not) of creating Windows spanned volumes from LUN delivered by a SAN ? I don't know which kind of SAN is (we don't administer it), but they give us 10 300 Gb LUN to our Windows 2k8 R2 (Vmware) and we need larger volume so we think to spanned some disk but we are aware of the performance issue. Any input ? Regards.

  • Can't add HKCU entries via GroupPolicy Preferences

    - by Lou H
    2008 R2, XP and W7 64 bit workstations. Trying to add/modify two registry entries for Lync2010 for each user. Created using GP Management, User Configuration, Preferences, Registry. If the two registry entries already exist, then the policy works correctly. If they don't exist, nothing changes. GPReults reports it was successful. If I import the .reg file manually, it also works, so I don't believe it is a rights issue. I have tried the Update, Create, and Replace as the Action. I am not familiar with ADM templates, is that the only way to do it?

  • What are the mandatory Linux kernel modules to run inside of ESXi

    - by Marcin
    I'm used to rolling my own kernels for servers, as it nicely minimizes the number of exploits (and the resulting patches) to take care of. In a traditional (bare metal) world, the whole process is about knowing what you have (hardware), and what you need (Ethernet, IPv4, iptables, etc.) In a virtualized environment, some things stay the same (still need Ethernet and IPv4), some things go away (power management), and then there are some new needs (vxnet3, or vmware-tools, even though that's compiled outside of the kernel). So my question mostly concerns itself with the last two categories: what can I remove completely, and what new stuff do I want? For example, what IO scheduler do I want, if all my disk operations are going through another filesystem/scheduler/cache to get to the virtual disk? Do I need hyper-threading enabled, or is the VM going to show them to me anyway as a CPU anyway? Do I need Large Receive Offload turned on, or is that something that the hypervisor's network drivers are going to do for me?

  • Can you have a WMI query for GPO Filter based on user's OU?

    - by Jordan Weinstein
    I'm wondering if there is a way to have a WMI query check the OU of the user logging on. I'd like a GPO (linked to Citrix servers OU) to apply only to users if the user is in a certain OU - this is for Citrix so the overly obvious answer of - well just link it to the OU the user is in does not apply. This also cannot be done using security groups because a long time ago those started to get used as Distribution Groups also and now too many are widely inaccurate. Lastly I need to apply this to the entire GPO as there are more than just group policy preferences included so I can't use the item-level targeting feature either. But my OUs are accurate so I'd like to use those if I can. I'd like a WMI query filter to say, apply GPO if user is member of OU 'x' that doable?

  • Are swapped in hot-swap drives allocated the same Windows drive letter each time?

    - by Margaret
    We are intending on purchasing a dedicated machine to perform the company's backups. We were considering buying the Dell T310, with the theory that we could swap the drives in and out for offsite backup. (As in, take out a drive, put a version a couple of days' old in its place, the old backup is updated to the current version.) One thing that may stymie this, though, is the system changing drive letters as things get moved in and out. Does anyone know whether this happens?

  • hp DL380 G4 won't boot with disk plugged into front USB

    - by Kev
    We outgrew a few older external USB backup drives, and purchased WD My Passport 1 TB USB 3.0 drives to replace them. When they are plugged into the front of our G4, it will blink forever after the BIOS (which is current, BTW) and never boot, even though the USB disks are not "bootable" per se. Our old drives did not exhibit this behaviour (so I don't think it's this type of issue that I've read about other servers.) The old drives were USB 2.0, but this shouldn't make a difference, AFAICT--the specs say all of the G4's USB ports are the same, 2.0, anyway, so I'm not sure how one port would handle a USB 3.0 device better than another. If we plug the new drives in one of the back slots, it boots fine. What's the cause? My concern is that the front USB port, and possibly the motherboard, might be starting to die. (We are experiencing other strange issues with them, or were initially, like intermittent file permissions errors despite wide-open ACL on these local drives, but some serverfault users have me convinced they may be coincidental software/security related issues.)

  • What's more cost effective, Hosting your web startup on Foss or Windows?

    - by user37899
    Hi, Not coming from the windows world, I'm confused about licensing. I think my knowledge may be out of date. Before we gave up with windows web servers (IIS 2), we used to have to pay Client Access licence's. This worked out quite expensive. Is it cheaper to host 1000's of users on Windows than use Free open source software tools? http://serverfault.com/questions/124329/network-load-balancing-efficience-and-limits. This post suggests I can pay $15 a month, for unlimited users. I certainly hope that this is unbiased view, I am a professional and use the right technology for the right job. I hope i am not feeling the wrath of a windows (or linux for that matter) fanboy. Perhaps a Microsoft certified Licensing person can clear this up. Should i be recommending to startups windows servers and products over lamp? Cheers!

  • Windows 2003 registry corrupt - endless reboot

    - by Jack
    Windows 2003 will run the loading screen then it stop with "Stop c000218 registry file failure or corrupt. The registry can not load the hive \systemroot\system32\config\security" then it start a count down about dumping the physical memory to disk and reboot itself again. I found Error starting Windows SBS 2003 - STOP: c0000218 but the config is different directory than mine. Is it the same step to try for recovery console?

  • RDP failing due to Audit Failure on the IPSec driver

    - by paulwhit
    I am trying to RDP into a Windows 7 Hyper-V image connected to a corporate network that publishes IPSec policies via Active Directory. I am seeing this error in the log: IPsec dropped an inbound clear text packet that should have been secured. If the remote computer is configured with a Request Outbound IPsec policy, this might be benign and expected. This can also be caused by the remote computer changing its IPsec policy without informing this computer. This could also be a spoofing attack attempt. Remote Network Address: XXX.XXX.XXX.XXX Inbound SA SPI: 0 How do I change my settings on the computer using RDP to something suitable for the domain-joined Hyper-V image?

  • MD3200i Slow Performance and Queue Depth

    - by Caleb_S
    Read performance on our SAN is slow under certain workloads. When we compare this to some local storage, we find the local storage performing 2x as fast. The SAN performs well with a high Queue Depth, and poorly with a low queue depth. However, the local storage performs well with a low Queue Depth. I'd like to know the reason for this occurring and find out what the specific limiting factor is in this situation. MD3200i iSCSI SAN ($15,000) 6 x 600GB 15k SAS RAID5 6 x 2TB 7.2k NLS RAID5 XCOPY /j Benchmark: (Slow) 15k Array - 71MB/s (Queue Depth 1) 7.2k Array- 71MB/s (Queue Depth 1) Robycopy /MT:32 Benchmark: (Fast) 15k Array - 171MB/s (Queue Depth ~12) 7.2k Array- 128MB/s (Queue Depth ~12) , , Read Performance on a Local controller is fast under the workload the SAN is slow at. , HighPoint 2230 RAID Controller ($600) 4 x 1TB 7.2k SATA RAID5 XCOPY /j Benchmark: 7.2k Array - 145MB/s (Queue Depth 1) (appears to max out the SATA bus)

  • Immediate Propagation in Active Directory

    - by squillman
    It's been a while since I've done any large-scale AD administration so I'm reaching back a bit here. I remember that there are certain security related attributes on a user account object that, due to their nature, are flagged for immediate propagation to other sites. I have a case where passwords resets are not being propagated until scheduled replication happens. I had thought that was a case of immediate propagation. Am I just remembering incorrectly? Domain function level is 2003.

  • Is it possible to find deleted objects in active directory without the assistance of a DLP software?

    - by Itai Ganot
    It seems like a large number of security groups have been deleted from the organization's AD. i was able to find the tombstones but i see there 1400 objects from the last 180 days and i know for certain that the important groups which have been deleted, have been deleted somewhere between yesterday's night and now. Is there a way, maybe by using power shell to extract the names of all objects which have been deleted through out the night? Thanks in advance Itai

  • scalable yet doable small-medium office network

    - by Jared
    Hello, I'm studying up with both Microsoft and Cisco literature and I must say, my head is starting to get clustered up (pun intended). I've made a quick network diagram of a theoretical company... Company1 owns Company 2 and Company 3, which are all under separate rooms and networks, but must be able to share a few resources such as files or printers. Given the amount of info out there and best practices, I thought about posting here to get suggestions and see what would the pro's do. I can read and read all day and implement on my own, but if I dont get some outside input, how will I know if I'm doing something wrong, right? anyway, please take a look and see if this is an over-complicated network or a lackluster design for a small-medium company of about 35 people and lets say they will be double that number by end of the year... :) Using win2k3, esxi, windows xp. FCS - forefront client security, ACS - access control system, SPCWK - spiceworks, XCH - Exchange Im not allowed to post an image yet, so here's the link ---- GLIFFY IMAGE Flame suit is on just in case people get mad at me for making an "abomination". I'd really want to get the general overview properly before I dive into the more complicated things

  • Solr startup script problem

    - by Camran
    I have installed solr and it works finally... I have now problems setting it up to start automatically with a start command.

  • Windows 2008 R2 large file copy causes Hyper-V Manager to stop responding

    - by maryeileen
    I'm using the EXPORT feature in Hyper-V to move a large Virtual Machine (VM) over a 1GB network from a Windows 2008 to a Windows 2008 R2 box (200GB) and its so intense that I get the following icon on my destination Hyper-V manager: Is this expected? Is there another way to get large file across the network and minimize this intense I/O effect? Anyones else ever seen that Do Not Enter sign? The other VMs are functional but slow, but I'm guessing that is expected.

  • Deleted one membership table. Possible to import without breaking relationship?

    - by superexsl
    Hey, I hope this isn't going to be tricky/time consuming, so fingers crossed. I'm working with the ASP.NET membership table. However, I've got quite a few other tables that I've built, and most of them have a relationship with the dbo.aspnet_Membership table. I've accidentally deleted the dbo.aspnet_Membership table and can't get it back. There was no major data on it, (as it's on my local machine), but I would really like to copy and paste that one table from another database I have, mainly for the sake of not breaking the schema. Is this possible? I'm worried if I run the Aspnet_regsql.exe tool, it's going to break the schema and remove all data from the tables as well the relationships (which would take a while to re-establish). Is there any way I can import just the dbo.aspnet_Membership table into my current database? Thanks for the any advice!
