• Microsoft Excel Error

  - by Chris

  I am working with a user that has Office 2007 installed. When they open excel with a blank workbook and then they try to close excel without having done anything, it gets hung for about a minute or two and then gives the warning message: "Microsoft Office Excel is waiting on another application to complete an OLE action." Has anyone ever seen this happen before? If so can you please help me figure out how to resolve this. It doesn't matter what excel file they open or if it is a blank/new workbook. Please Help.

• Windows 7 Laptops "unable to find logon server"

  - by tombull89

  In the school I work in we have a large number (500+) of Windows 7 laptops on a Meru Wireless system and Server 2008 R2 Servers. We have an appalingly large failure rate where a student or staff member tries to logon (to the laptop joined to the domain) and is met by "There are currently no logon servers available to service the logon request". I've seen this question and this one and while removing and re-joining to the domain works, it's highly time consuming, irritating, and we (I) have more important things to concentrate on. The only MS KB article I can find is regarding a read-only domain controller (which ours isn't) and I'm at my wits end. Ultimately, is there a definitve cause and answer to this or am I stuck removing and re-joining the laptops?

• Cisco PIX 515 doesn't seem to be passing traffic through according to static route

  - by Liquidkristal

  Ok, so I am having a spot of bother with a Cisco PIX515, I have posted the current running config below, now I am no cisco expert by any means although I can do basic stuff with them, now I am having trouble with traffic sent from the outside to address: 10.75.32.25 it just doesn't appear to be going anywhere. Now this firewall is deep inside a private network, with an upstream firewall that we don't manage. I have spoken to the people that look after that firewall and they say they they have traffic routing to 10.75.32.21 and 10.75.32.25 and thats it (although there is a website that runs from the server 172.16.102.5 which (if my understanding is correct) gets traffic via 10.75.32.23. Any ideas would be greatly appreciated as to me it should all just work, but its not (obviously if the config is all correct then there could be a problem with the web server that we are trying to access on 10.75.32.25, although the users say that they can get to it internally (172.16.102.8) which is even more confusing) PIX Version 6.3(3) interface ethernet0 auto interface ethernet1 auto

• Can I use dmraid instead of md (mdadm) to make software RAID-1 and RAID-1+0 volumes?

  - by Don MacAskill

  On a related question about SSDs and TRIM (see: Possible to get SSD TRIM (discard) working on ext4 + LVM + software RAID in Linux? ), it turns out that dmraid may now (or shortly) support TRIM on RAID-1. Typically, we've used md (via mdadm) to create our RAID-1 volumes, then used LVM to create volume groups, then formatted with the file system of our choice (ext4 lately). We've been doing this for years, and Google & ServerFault searches seem to confirm this is the most common way of doing software RAID with volume management. Google searches seem to suggest that dmraid is use for so-called 'fakeRAID' configurations where there's some level of hardware 'help' in the form of RAID BIOS in the controller, which we don't have (and don't want to use - we'd like a fully software solution). Since we'd like to use TRIM on our SSDs, and since md doesn't seem to (yet?) support TRIM, I'm wondering if it's possible to use dmraid instead of md to create RAID-1 (and RAID-1+0) volumes in software, with no hardware support (ie, just plugged into a dumb SATA/SAS bus)?

• How can I access the external microphone with Ubuntu?

  - by Charles Merriam

  Sound in Ubuntu, it has its own special joy. I would like my external microphone to work. Symptoms: I can play sound through the speakers I can play sound through the headsets. Plugging and and plugging headphone output correctly switches. I can record from the built-in microphone, using "Sound Recorder" and others. but: I cannot record from the external microphone. My Sound Preferences/Input panel has no option for an external microphone. If the answer is upgrade the ALSA drivers, please say exactly what to type. Thank you. ======== I'm using Ubuntu 9.10 Karmic Koala on a laptop (Gateway W3501), Sigmatel. That is: ~$ head -1 /proc/asound/card0/code* ==> /proc/asound/card0/codec#0 <== Codec: SigmaTel STAC9205 ==> /proc/asound/card0/codec#1 <== Codec: Conexant ID 2c06 ~$ lspci | grep -i audio 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

• Error when trying to add additional mailbox in Outlook: The name could not be resolved.

  - by Jon B

  I am trying to open an additional mailbox in Outlook 2003 for one of my users. She already has three additional mailboxes in the list (found in the advanced account settings), and these work fine. When I click the "Add..." button, it immediately reports: The name could not be resolved. The action could not be completed. This is before I am prompted for the name. We're using an externally hosted Exchange 2007 server. How do I resolve this?

• Server 2012 R2 DNS Conditional forwarding not working reliably, possible caching issue?

  - by Matt

  I have a bit of a home lab setup with a domain controller that is acting as the DNS server for my network. For everything, it's working fine and forwards external DNS requests to my ISP. The household recently wanted to get Netflix going and it seemed a DNS option was better than a VPN to get around the region locking, so I signed up for unblock-us.com Since I have a Windows DNS server I thought I'd be clever and make use of conditional forwarders and added the Netflix domain to the list. Initially this worked well and all devices on the network could now access Netflix, however after about an hour going to the Netflix site would result in a page cannot be found. Doing an nslookup of Netflix.com from my PC resulted in it not returning any IP addresses. As a test, I deleted the Netflix domain from the DNS servers cache and things started working again - devices could get to the site again however the same thing happens again after around half an hour to an hour. Have I missed something here that's causing it to stop working?

• Create and use intermediate certificate authority on Windows Server 2012?

  - by Sid

  Background: Server OS is Windows Server 2012. GUI is installed as we come upto speed with powershell. Setup is staging, not production (yet). We have our (internal, domain limited) Root CA installed. I would like to take the Root CA offline to secure storage but before that I'd like to setup an intermediate CA which can take over actual live, online (int-RA-net) functionality Can someone guide me covering: creating the intermediate CA certificate request installing the intermediate CA certificate on domain controller (certification authority role already installed with Root CA online right now) use the intermediate CA to generate a certificate (any use certificate, just for demonstration purposes) Obviously this certification chain would be invalid on computers outside our domain (self trusted root - our root certificate is NOT from common 3rd parties). This last point is NOT a problem.

• Domino 8.5.3: Modify Subject of Incoming Email

  - by Void

  I am a newbie in managing and development for Domino. Recently, I have request from other teams at work to set up a filter or agent for incoming mail. This is the requirement for the request: Look for Incoming Mail addressed to #CRITICAL (mutlipurpose, internal group containing a list of engineers) For mail matching Point 1, append "For Immediate Action: " to the front of the Subject Some restrictions I have: Only the Domino server is under my charge, not to touch on network-side or other servers No 3rd party software to be installed I have gone through the configurations in the Domino server and the closest thing I have to filtering Email is the Router/SMTP Restrictions... Rules. But this is not able to fulfill Point 2 in any way. Is this even possible using just Domino server settings, or through agents?

• Upgrading OpenSSL in CentOS 5.3

  - by Lin

  I want to use one IP to host many domains with individual SSL certificates (requires SNI). In CentOS 5.3, the latest version of OpenSSL I can find an RPM for is 0.9.8e, which does not support SNI. I want to upgrade to 0.9.8k but I can't find an RPM. I could compile from source, but if I try to remove the existing OpenSSL package through yum, it wants me to remove all packages that depend on OpenSSL (100+ packages). EDIT: I ended up installing 0.9.8k without overwriting the previous version. Now I both avoid breaking dependencies and can use SNI. Was this the best action?

• Local User & Local Admin User Server 2008

  - by Ammo

  Hi I had a test recently and one of the questions was to create a file and local user and give the local user write permission to that file. I created the local user successfully however when I went to add permission to the file it would not find the local user when name was entered correctly, and idea what could have prevented this. Secondly I was asked to create a local admin account and give full permissions to the file, to my knowledge server 2008 has a built in admin account, and neither was the server a domain controller. Could you tell me what you would do in this situation? Many Thanks!

• AD, Windows-NT Authentication queries

  - by rockbala

  Need Help on the following questions. When a users login (on a computer in the network) is validated against AD what is/are the authentication method used? When a users login is validated in Windows NT environment (not AD) what is/are the authentication method used? If all user's account is on AD, is it possible to change the authentication mechanism only (or protocols) from AD to NT and vice versa (if possible)? If part/whole of question 3 is valid, where should one look to change these authentication methods ? What is the difference between AD and Windows-NT authentication ?

• How disable Apple iCal from popping up with every email invite/update?

  - by Sean

  My iCal has new behavior (since upgrading to SL). Every time I get an ical attachment in Mail, the iCal app flies up in my face. I don't see any way to turn off this behavior and it's amazingly disruptive when I'm busy with other activities. Help? EDIT: I want iCal to add the invitations, so when I cmd-tab to the app those items are in the queue awaiting approval. What I am hoping to learn is how to stop the popup action forcing the application to become the top-level window.

• Authorization error when testing FTP to UNC

  - by user64204

  We have a Windows Server 2008 R2 with Active Directory (hereafter called DC) running as a domain controller on which we have IIS and an FTP site installed. We have a second Server 2008 (hereafter called SHARE) which is joined to that domain and has a disk shared as a network share (\\share\Office). That network share is used as the ftp's physical path on DC. We've tested the FTP from the IIS FTP configuration panel, by clicking on Basic Settings... then Test Settings.... When setting Administrator as a username with the Connect as... option, everything is fine: When no user is provided we can the below error: Q1: Could someone explain in more understandable terms what is written in the Details text area?

• ZFS and SAN -- best practices?

  - by chris

  Most discussions of ZFS suggest that the hardware RAID be turned off and that ZFS should directly talk to the disks and manage the RAID on the host (instead of the RAID controller). This makes sense on a computer with 2-16 or even more local disks, but what about in an environment with a large SAN? For example, the enterprise I work for has what I would consider to be a modest sized SAN with 2 full racks of disks, which is something like 400 spindles. I've seen SAN shelves that are way more dense than ours, and SAN deployments way larger than ours. Do people expose 100 disks directly to big ZFS servers? 300 disks? 3000 disks? Do the SAN management tools facilitate automated management of this sort of thing?

• Windows 7 trying to turn off UAC every time Windows starts

  - by Mehper C. Palavuzlar

  I have strange problem on my HP laptop. This began to happen recently. Whenever I start my machine, Windows 7 Action Center displays the following warning: You need to restart your computer for UAC to be turned off. I never disable UAC, but obviously some process or virus (I'm not sure, only guessing) causes this. As soon as I get this warning, I head for the UAC settings, and re-enable UAC to dismiss this warning. This is a bothersome situation as I really don't know what causes the problem. I have run a full scan on the computer for any probable virus activity, but TrendMicro OfficeScan said that no viruses have been found. There are no other strange incidents on the machine. Everthing works fine except this bizarre incident. How can I learn what process is trying to turn off UAC? What way should I follow to overcome this problem?

• iSCSI RAID1 on two servers, fail scenario

Two questions: Can I do the merging of the 4 disks in one go? I can't image how. First I will have to install the os, and then the raid controller is already set up to RAID1. If a whole server fails the other server would continue working without any problems? Does iSCSI notice that the other server is missing and treet this as if the two disks were broken? When the server comes back online the data is resynced, as if I installed new disks into a array? Can I image that this way? Thanks alot.

• How disable Apple iCal from popping up with every email invite/update?

  - by Sean

  My iCal has new behavior (since upgrading to SL). Every time I get an ical attachment in Mail, the iCal app flies up in my face. I don't see any way to turn off this behavior and it's amazingly disruptive when I'm busy with other activities. Help? EDIT: I want iCal to add the invitations, so when I cmd-tab to the app those items are in the queue awaiting approval. What I am hoping to learn is how to stop the popup action forcing the application to become the top-level window.

• HP Proliant DL360 G5 + MSA50 RAID Setup recommendations

  - by JohnRB

  I am running a HP Proliant DL360 2 x 3GHz Xeon 16GB Ram P400 integrated RAID card with 6 x 73GB SAS HDDs running Ubuntu Server 14.04 CLI only. I recently got my hands on a MSA50 SAS Enclosure (10 x SAS HDD bays w/ SAS in/out interface) and wondering what you guys recommended as far as an addon raid controller for one of the pciex slots. I have both slots free Full and Half sizes. Any suggestions are greatly appreciated, I am an I.T. Consultant but have not used these particular units before so I was hoping to hear from someone who has. Thanks!

• FreeNas running on ESXi - sometimes gets very slugish.

  - by Luma

  Hello everyone, I have a ESXi server (dual quad core, 8GB of DDR3 ram, 6x 1TB WD Blacks running in RAid 5 on the PErc 6/i controller. I have a 64bit freenas VM running, on this VM I keep about 200Gigs of stuff that my windows machines access. every now and then the throughput of this VM just dies, for example right now it can't even handle streaming a song and when I tried to transfer a folder the speed goes from 10-400KB/s. Might I add at this point that the ESXi box has dual gigabit network cards plugged into a good solid gigabit switch and other linux and windows VM's are just fine I have seen speeds over 90MB/s (frequently) The server still has ram left over (plenty actually) and cpu is very low (500-1000mhz) any ideas what could cause this? thanks.

• Need advice to choose correct wi-fi drivers for Dell Vostro 3560

  - by overdriven

  I'm having problems with my Dell notebook's Wi-Fi, it can't see some of the available access points, despite they are close and I used to be connected to them yesterday. Other notebooks and my phone can see them. I believe it's a driver issue, since after installing system I haven't downloaded any network drivers. I went to Dell's website to search for them but I have no idea which should I choose. For my Dell Vostro 3560 and system Windows 8.1 64bit these are available: Intel Smart Connect Technology Application APP_iSCT_W8.1_A00_Setup-TJW84_ZPE.exe (23 MB) Vostro-3560_Network_Application_TJW84_WN_4.2.40.2418_A00.EXE (29 MB) Dell Wireless 1704 WLAN 802.11b/g/n (2.4GHz), Bluetooth v4.0+HS Driver DW1704_W8.1_A00_Setup-K1HGN_ZPE.exe (239 MB) Network_Driver_K1HGN_WN_6.30.223.143_A00.EXE (247 MB) Dell Wireless1703 802.11 b/g/n, BT4.0 + HS Driver Dell Wireless1901 802.11a/b/g/n (2.4GHz and 5GHz), Bluetooth v4.0+HS Driver DW1703_DW1901_Win8.1_A00_Setup-7FPWR_ZPE.exe (265 MB) Network_Driver_7FPWR_WN_10.0.0.263_A00.EXE (272 MB) Realtek RTL8105E/RTL8111E Ethernet Controller Driver LOM_Realtek_W8.1_A00_Setup-0XCVW_ZPE.exe (6 MB) Network_Driver_0XCVW_WN_8.018.0621.2013_A00.EXE (12 MB) Intel® Centrino® Wireless-N 2230 Bluetooth Driver BT_Intel_W8.14_A00_Setup-XR83W_ZPE.exe (31 MB) Network_Application_XR83W_WN_3.1.1307.0362_A00.EXE (37 MB)

• modify the way files get opened from finder by shift-clicking (etc) as in windows

  - by stib

  In the windows shell it is possible to modify the default action for opening any document type when holding down a modifier key such as shift or option when double clicking. So for example I can open a jpeg in irfanview if I just double click it, in firefox if I shift-double click it or in potatoshop if I option-double click it. However on a mac I have to right click, and choose "open with..", which can be annoying when there are a lot of possible candidates (such as with jpegs) or if I want to open the file with somehting like an applescript, which won't show up on the list and will have to be found in the file system and specified manually, every.. single.. time. Is there a way of making the mac open files differently by holding down modifier keys when double clicking?

• HP DL380 G5 Predictive Drive Failure on a new drive

  - by CharlieJ

  Consolidated Error Report: Controller: Smart Array P400 in slot 3 Device: Physical Drive 1I:1:1 Message: Predictive failure. We have an HP DL380 G5 server with two 72GB 15k SAS drives configured in RAID1. A couple weeks ago, the server reported a drive failure on Drive 1. We replaced the drive with a brand new HDD -- same spares number. A few days ago, the server started reporting a predictive drive failure on the new drive, in the same bay. Is it likely the new drive is bad... or more likely we have a bay failure problem? This is a production server, so any advice would be appreciated. I have another spare drive, so I can hot swap it if this is a fluke and new drive is just bad. THANKS! CharlieJ
