• Explorer.exe not starting after login on Windows Server 2003 (Terminal Services and console)

  - by Pepperoni Icecream

  When users login to a Windows Server 2003 R2 running Terminal Services they have a blank desktop. Upon inspection, explorer.exe is not running. When I login as administrator, using either RDP or to the console, I am having the same issue. I can pull up the taskman and start explorer.exe manually. I have another Terminal Server setup exactly the same way (same apps, settings, GPO, etc . . .) the only difference is we deployed Symantec Endpoint Client 11.0.5 on Friday. For some reason the working Terminal Server is still on 11.0.4, but the suspect server received the 11.0.5 client upgrade. I checked the eventviewer for any relevant explorer.exe entries to no avail. It seems that if SEP is preventing explorer.exe from starting at login it would do the same for the domain admin starting explorer.exe from the taskman. I disabled the SEP client and services on the server and issued smc -stop and tried logging in again. Still no explorer.exe. So I'm not sure if the client upgrade is relevant but it is worth mentioning since that was the last system change. The 2 servers are members of a NLB group. I took the bad terminal server out of the group until the issue is resolved. Actually stopped the host using NLB manager Any help is appreciated.

• Increasing Java's heapspace in Tomcat startup script

  - by Ankur

  I want to increase my heap size when using Tomcat. I was told to add this line export CATALINA_OPTS=-Xms16m -Xmx256m; In to the startup.sh script - I did so (at the beginning) but got the error export: 24: -Xmx256m: bad variable name Where am I supposed to add it, am I doing something else wrong? <b>export CATALINA_OPTS=-Xms16m -Xmx256m;</b> # Better OS/400 detection: see Bugzilla 31132 os400=false darwin=false case "`uname`" in CYGWIN*) cygwin=true;; OS400*) os400=true;; Darwin*) darwin=true;; esac # resolve links - $0 may be a softlink PRG="$0" while [ -h "$PRG" ] ; do ls=`ls -ld "$PRG"` link=`expr "$ls" : '.*-> \(.*\)$'` if expr "$link" : '/.*' > /dev/null; then PRG="$link" else PRG=`dirname "$PRG"`/"$link" fi done PRGDIR=`dirname "$PRG"` EXECUTABLE=catalina.sh # Check that target executable exists if $os400; then # -x will Only work on the os400 if the files are: # 1. owned by the user # 2. owned by the PRIMARY group of the user # this will not work if the user belongs in secondary groups eval else if [ ! -x "$PRGDIR"/"$EXECUTABLE" ]; then echo "Cannot find $PRGDIR/$EXECUTABLE" echo "This file is needed to run this program" exit 1 fi fi exec "$PRGDIR"/"$EXECUTABLE" start "$@"

• Script to unstick VNC keys?

  - by MidnightLightning

  I've run into dropped key events when connecting via VNC clients, leading to a "stuck key" (usually a meta key like CTRL or ALT) and searching around the common answer on how to solve it is often "press and release each meta key individually until the problem resolves". However, I've found this to be annoying and time consuming to try and solve it this way. Plus on a bad connection, it sometimes will miss the "key up" event for the meta key again, and still keep the key stuck. So I'm looking for an automated way to do this: From a script on the client side or the server side, is there a way to trigger "key up" events for all the meta keys (CTRL, ALT, SHIFT, and WIN/CMD, both Left and Right versions)? Or just a command to release all keys the server thinks are down at the moment? Or some scripted way to at least list which keys the server end thinks are down so I know which key to keep pressing and releasing to try and release it? I've got a Mac on the server end, so a Mac/Linux solution would be needed for my situation.

• I/O APIC on Virtualbox

  - by RidDeBakTiYar

  I'm trying to use the PIT to do APIC timer calibration, and I want to use the PIT through I/O APIC instead of PIC. On Bochs I get interrupts from the PIT at the asked frequency from the I/O APIC, while on Virtualbox I can't receive a single interrupt. It must be an I/O APIC configuration problem because as I unmask the first PIC entry, the IRQ fires. However that's not what I want. Can you imagine any possible condition that wouldn't make Virtualbox fire the IRQ? I'm not assuming single I/O APIC configuration (even though Virtualbox has only 1). I'm not assuming identity mappings between ISA IRQs and I/O APIC GSIs (using ACPI MADT table to get I/O APIC base address and Int override). I'm setting the Trigger Mode and Polarity bits correctly (on Virtualbox they are set as '00 - default' which means edge high right?). I'm putting the BSP APIC ID into the Destination field (using Physical destination) and vector 0x20. Being the BSP APIC ID 0 on Virtualbox, it ends up with 0x0000000000000020 written to the IOREDTBL. And, just in case I'm getting the wrong values from the Interrupt Override descriptor, I'm setting this value to all the IOREDTBL entries (I know this is very very bad, and it wont be kept as I understand what's going on). The only thing I didn't check out is Local APIC configuration. Actually I'm not writing any value to the BSP LAPIC. Just reading the APIC ID and using it to boot APs through IPIs. And obviously I'm setting bit 11 in the IA32_APIC_BASE MSR to enable the LAPIC. Any ideas? Thanks in advance.

• How use DNS server to create simple HA (High availability) of my website?

  - by marc22

  Welcome, How can i use DNS server to create simple HA (High availability) of website ? For example if my web-server ( for better understanding i use internal IP in real it will be other hosting companies) 192.168.0.120 :80 (is offline) traffic go to 192.168.0.130 :80 You have right, i use bad word "hight avability" of course i was thinking about failover. Using few IP in A records is good for simple load-balancing. But not in case, if i want notice user about failure (for example display page, Oops something is wrong without our server, we working on it) against "can't establish connection". I was thinking about setting up something like this 2 DNS servers, one installed on www server Both have low TTL on my domain, set up 2 ns records first for DNS with my apache server second to other dns If user try connect he will get ip of www server using first dns, if that dns is offline (probably www server is also down) so it will try second NS record, what will point to another dns, that dns will point to "backup" page. That's what i would like to do. If You have other idea please share. Reverse proxy is not option, because IP of server can change, or i can use other country for backup.

• Update git on mac

  - by Meltemi

  I can't remember how I installed git a while back....but now it's living in /usr/bin/git and needs to be updated. I don't care how (pre-compiled or build my own) but what I don't want is another version existing somewhere else. i vaguely remember curl(ing) down the source & compiling it. but not positive. anyway, what's the easiest way to keep Git up-to-date under Mac OS X? Side question: I'm not that familiar with git. once it's installed is it ENTIRELY contained within its directory? so, in my case, everything about git on my machine (excluding the actual code repositories of course) is in /usr/bin/git/ ? If so then can I just move git around with a simple mv -R /usr/bin/git /opt/git? Then update my $PATH and everything should work as before? if so then i supposed i could just install again by any method and to any directory...and then move the new one into /usr/bin replacing the old version?!? Or is this bad?

  I'm trying to fuzz a server using the Sulley fuzzing framework. I observe the following stream in Wireshark. The error talks about a problem with JSON parsing, however, when I try the same HTTP POST request using Google Chrome's Postman extension, it succeeds.

• apache with php fastcgi keeps going down

  - by Josh Nankin

  I have an apache2 server configured with MPM worker and php fast cgi. Lately the apache logs have been telling me that MaxClients is being reached frequently, even though it's already pretty high. My server is now constantly going down, and I see a bunch of lines like this in the log: [Sun Mar 06 04:25:40 2011] [error] [client 50.16.83.115] FastCGI: comm with (dynamic) server "/var/local/fcgi/php-cgi-wrapper.fcgi" aborted: (first read) idle timeout (20 sec) [Sun Mar 06 04:25:40 2011] [error] [client 50.16.83.115] FastCGI: incomplete headers (0 bytes) received from server "/var/local/fcgi/php-cgi-wrapper.fcgi" I can see that my php-cgi processes are pretty large (about 70mb on average).

• InstallShield or Windows installer corrupted

  - by Bobby S

  Just recently I've been unable to install any software on my Windows 7 machine. Anything that uses InstallShield or the Windows installer will just hang or give a weird error. I noticed there will be many duplicate isbew64.exe processes (like 25) that launch and then just sit there or else a lot of msiexec.exe *32 processes, depending on what I'm trying to install. One piece of software specifically is the Logitech Harmony software. It gives me an *is_string_not_defined* error, saying c:\program files (x86)\:\ the filename, directory name, or volume label syntax is incorrect. The other thing I was trying to install was Battlefield: Bad Company 2, and that just hangs as well, and then just leaves all the Windows installer processes running in the background after I quit the install process. Very odd. I've checked well and googled these issues, it doesn't appear to be any sort of malware issue. I feel like it's related to some kind of corrupted installer application. I've rebooted, deleted the InstallShield folder in program files/common files as some places online suggested but to no avail. I have no idea what to do, any ideas?

• Problem posting multipart form data using Apache with mod_proxy to a mongrel instance

  - by Ryan E

  I am attempting to simulate my site's production environment as closely as I can on my local machine. This is a rails site that uses Apache w/ mod_proxy to forward requests to a mongrel cluster. On my Mac OSX Leopard machine, I have the default install of apache running and have configured a vhost to use mod_proxy to to forward requests to a local running mongrel instance on port 3000. <Proxy balancer://mongrel_cluster-development> BalancerMember http://127.0.0.1:3000 </Proxy> For the most part, this is working fine. I can browse my development site using the ServerName of the vhost I configured and can confirm that requests are being properly forwarded to the mongrel instance. However, there is a page on the site that has a multipart form that is used to upload an image to the server. When I post this form, there is a delay of about 5 minutes and the browser ultimately returns a Bad Request Your browser sent a request that this server could not understand. In the error log for my vhost: [Tue Sep 22 09:47:57 2009] [error] (70007)The timeout specified has expired: proxy: prefetch request body failed to 127.0.0.1:3000 (127.0.0.1) from ::1 () This same form works fine if I browse directly to the mongrel instance (http://127.0.0.1:3000). Anybody have any idea what the problem might be and how to fix it? If there is any important information that I neglected to include, post a comment, and I can add to this question. Note: Upon further investigation, this appears to be a problem specific to Safari. The form works fine in Firefox.

• Nginx + PHP5-FPM repeated cut outs 502

  I've seen a number of questions here that highlight random 502 (Nginx + PHP-FPM = "Random" 502 Bad Gateway) and similar time outs when using Nginx + PHP-FPM.

• How harmful is a hard disk spin cycle?

  - by Gilles

  It is conventional wisdom¹ that each time you spin a hard disk down and back up, you shave some time off its life expectancy. The topic has been discussed before: Is turning off hard disks harmful? What's the effect of standby (spindown) mode on modern hard drives? Common explanations for why spindowns and spinups are harmful are that they induce more stress on the mechanical parts than ordinary running, and that they cause heat variations that are harmful to the device mechanics. Is there any data showing quantitatively how bad a spin cycle is? That is, how much life expectancy does a spin cycle cost? Or, more practically, if I know that I'm not going to need a disk for X seconds, how large should X be to warrant spinning down? ¹ But conventional wisdom has been wrong before; for example, it is commonly held that hard disks should be kept as cool as possible, but the one published study on the topic shows that cooler drives actually fail more. This study is no help here since all the disks surveyed were powered on 24/7.

• Computer locking up, looking for bootable hardware diagnostic tool.

  - by Carl Menke

  Well today I helped my friend build a computer. All went pretty well until we got to installing Win7. Thing is, we thought, it was crashing constantly. I adjusted pretty much every setting in the BIOS and removed as much hardware as possible to try and prevent a crash. No dice. So far I've tried running an Ubuntu live cd without the harddrive installed. Nope, crashed on boot. And then I just tried Microsoft's ram utility disk and it eventually locked up on that (the ram passed though). So it seems to me like it's either the CPU (AMD PhenomII x3) or the motherboard that could be bad, but I don't know how to test them individually for problems. I thought it could be a overheating issue, but the BIOS reports that the CPU temp is fine idling around 34C. Any advice or diagnostic disk that could help me out? TL;DR: Computer locks up frequently during use (cannot even boot/install an operating system), memory is fine, probably CPU or Mobo, BIOS says CPU temps are fine. What should I try?

• Why do I get a DegradedArray event with mdadm

  - by azera

  Hello Just so we're clear on what's happening: I bought 4 new sata 2 drives, with the intent of using them in a raid5 all drive are fully recognised by both my bios and my linux box (gentoo) I created a raid5 array, fiddled a bit with it to understand how it works, how to monitor ect At some point, this triggered a degradedarray event, even though the array is brand new. I tried to stopping the array and recreating a new array with the same drive but the new array starts degraded too. here is what I used to create it mdadm --create -l5 -n4 /dev/md/md0-r5 /dev/sdb /dev/sdd /dev/sde /dev/sdf here are the output from my /proc/mdstat and mdadm --detail --scan **mdstat** Personalities : [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md127 : active raid5 sdf[4] sde[2] sdd[1] sdb[0] 4395415488 blocks level 5, 64k chunk, algorithm 2 [4/3] [UUU_] [>....................] recovery = 2.8% (41689732/1465138496) finish=890.3min speed=26645K/sec unused devices: <none> **detail** ARRAY /dev/md/md0-r5 metadata=0.90 spares=1 UUID=453e2833:81f22a74:64188b84:66721085 As such I have a couple questions: does a raid5 array always start in degraded mode at first ? why does sdf have the number 4 between bracket instead of 3, why does it see a spare disk and why is the 4th drive marked with _ instead of U ? (bad configuration ?) How can I recreate the array from scratch, do i have to format each drive on its own before recreating it ? Thanks for any help, I'm not sure about what I should do at the moment

• What's the state of the art in image upscaling?

  - by monov

  I like to collect cool pics and use them as wallpapers or for other things. Often, artists publish only low-res versions, probably for fear of theft. Example: Gabriel Pulecio's BIRDS Now, if I want to use that as a wallpaper, I'd have to upscale it, and obviously that'd make it look blurry because of the bicubic interpolation. I realize there's no real way to get a high-res version from a low-res pic, because the information is not simply there. That said, I'm wondering if heuristics have been developed for upscaling with less apparent loss of quality. Those would probably be optimized for specific image types. For photorealistic pictures, for cartoons with large flat areas, for pixel art... One algorithm I'm aware of is Seam Carving. It works for some kinds of pics, especially ones with a plain, undetailed or uninteresting background, and a subject that strongly stands out. But it's far from being general-purpose. Applying it to the above pic produces this. It looks quite sharp, but the proportions are horribly distorted because the algorithm is not designed for this kind of pic. Another is Pixel art scaling algorithms. Those are completely unfit for anything other than actual pixel art that's pixelized to begin with. For example, I tried the scale2x windows binary on my pic, but its output was nearly indistinguishable from nearest-neighbour scaling because the algorithm didn't detect any isolated pixely fragments to work from. Something else I tried was: I enlarged the image in Photoshop with bicubic interpolation, then I applied unsharp mask. The result looks pretty bad. The red blotch is actually resized reasonably well, but the dove is far from it. What I'm looking for is some app that makes a best-effort attempt at upscaling any input image while minimizing blurriness. If you know of any, I'll be thankful. Note that the subjective prettiness and sharpness of the result is what matters... the result doesn't need to be completely faithful to the original small image.

• Drobo FS vs Lime Technology unRAID vs FreeNAS

  - by elluca

  I already decided to by a drobo fs until I just found these two tests: http://www.digitalversus.com/data-robotics-drobo-fs-p889_9543_487.html http://www.digitalversus.com/lime-technology-unraid-p889_8992_473.html The two cons agains drobo for me: loudness price What disadvantages has the unraid stuff against the drobo fs? Has it also got that ease of use like swapping drives on the go, simply extend capacity by plugging in new drives, notify me of drive errors, disk failure protection, dynamic space of "partitions", better/worse effective capacity, etc. Which is more secure? Am I able to simply replace a bad drive with a new one on unraid? What happens if my pc fails? Lets say the cpu overheats. Since I have a complete pc which is going to be replaced, I only have to pay the software to use unraid. I am going to use my nas for: music library (how well does it integrate with iTunes? ) picture library movie library development (i need to be able to be to use time machine) I am going to use this nas with a MacBook pro. My current disks: 2x 500Gb 1x 1.5Tb 1x 2Tb On a drobo fs I would have 2.26 Tb of space. What would it be on unraid? Is FreeNAS also an alternative?

• Static noise in headphones

  - by John Murdoch

  I have a Asus P6T based system. I was using the on-board sound (plugging in Logitech X-230 2.1 analog speakers in the green "front speakers" 3.5mm analog output, then plugging in my headphones in that). I was quite happy with the sound quality (didn't hear any static noise if volume was turned down to my normal listening level). Then about a week ago I started having terrible static noise from the left channel, and no normal audio on that left channel. Right channel had more static noise than usual but did have a bit of sound. I tried using the AC'97 in front of my case but that seemed to have no signal. I decided my on-board sound card has gone bad and bought an internal sound card to replace it (Startech 7.1Ch PCI). This fixed the "no sound from left channel problem", but I had much more audible static noise. I decided the card was low quality and/or it had interference from all the other things happening inside the computer case, and bought a Sweex SC016 external USB sound card. But even with that I have static noise in headphones. Positioning the USB sound card differently doesn't seem to help. Trying the other analog outputs (e.g., surround) doesn't help. The static noise in all cases is proportional to the volume. I have tried different headphones, but the situation is situation though perhaps the flavour of the static noise changes slightly. So what are my options? a) Get another, more expensive, external USB sound card hoping the quality will improve? b) Get another, more expensive, internal sound card (PCIe 1x perhaps) hoping the quality will improve? c) Get a dedicated DAC box? d) Get some Hi-Fi earphones? Suggestions? tl;dr - Two different sound cards both still have static noise in headphones.

• VMWare Guest Info - Wrong IP Returned

  - by Jon Bailey

  We're running a VDI environment with vSphere 4.0 and Oracle VDI 3.2.2 and are having a bit of a problem with users that connect to an IPSec VPN from within their VM. For some reason, once connected to the VPN, the VMWare API returns GuestInfo.ipAddress as the VPN IP rather than the primary IP of the only NIC on the system. The IP address shown in net[0].ipAddress is the correct address and is what vSphere client is reporting. Is there any way to get VMWare tools to report the net[0].ipAddress as GuestInfo.ipAddress? Below is sample output from the guestinfo.pl script. 172.16.1.2 is the example "bad" VPN address that our VDI software is seeing.

• Hard Drive benchmark values show write very very slow

  - by John

  I recently started to have issues with my laptop being very slow. I ran a hard drive benchmarking tool (by ATTO) that showed that the write speed was very very slow on my boot drive. I ran the same benchmark on my usb drive and it was 650 times faster than my boot drive when it came to writing. Reading is very fast/normal on both. I swapped out an identical drive and ran the same benchmark. This time the drive showed proper write speed. Thinking that I had a hard drive going bad I cloned the old one onto the new one. I managed to clone the problem too. Anyone have any ideas on what in WinXP SP3 might be causing the write issues? I am on a corporate network and we have commercial anti-virus software installed. (AVG I think) I regularly run defraggler and have about 40 gig free on a 100 gig drive. The machine has 4 gigs of memory. Any ideas? TIA J

• vDS - vCenter Problem

  - by rbmadison

  We are implementing a vSphere farm and are using a distrubuted switch. The VC is a VM within the farm connected to the distrubuted switch. We had a SAN issue and all of our VMs were down. When the SAN recovered and we restarted the ESX host containing the VC the VC couldn't connect to the network through the vDS. We had to remove a NIC from the vDS on that host and create a regular vswitch and then connect the VC to that before the VC would connect to the network. Is this typical behavior? If the VC goes down does all vDS networking stop on all the hosts? That seems to be a very bad thing. I thought networking would work even though the VC is down because the hosts have the vDS configuration cached. Is there a better way to configure it to prevent this from happening. We want to keep the VC as a VM for HA and recoverabilty purposes. Can anyone offer suggestions or explanations? I appreciate the help. Thanks, Rick

• Windows XP corrupts registry every several hours

  - by Ilya Kazakevich

  There is a Dell XPS 400 with Windows Media Center installer. It is installed on RAID (Intel Matrix Storage) which is built-in chipset south bridge. Raid has two 150 Gb WDC drivers connected as mirror. All drivers and updates are installed( sp3 and so on). A week ago PC changed its video mode to 256 colors (like VESA mode) and after several moments I got BSOD: c000021a: 0xc0000005 Doctor watson did not create dump although it is installed as default debugger. After reboot it said that config file is missing or corrupted. So, I boot to recovery console and found that registry file (config) is so small. I've replaced it with one from recovery point and windows booted sucessfully. But after about 3 hrs -- it has crashed again in the same wat! I look in event viewer: is said that Explorer.exe failed to open \global??\DLIAFS. I look in winobj, and found that it is a device. I made "deny from everyone" for this device ACL, and after several hours my windows crashed. I restored registry, boot again and there was no error about DLIAFS. I did full chkdsk and it did not found anything bad. But I found event about error paging to \Harddrive1\D. I do not have pagefile there, but I thought I should check my disk again. Unfortunatelly I cannt use smart tools for RAID, but I downloaded latest software from Intel (it can do the same things like RAID bios can but from windows). It verified my disks, found some errors, fix them, than I rebooted. And it crashed again. I am lost. What (except kernel debugging) could be done here? Thanks

• Windows XP corrupts registry every several hours

  - by Ilya Kazakevich

  There is a Dell XPS 400 with Windows Media Center installer. It is installed on RAID (Intel Matrix Storage) which is built-in chipset south bridge. Raid has two 150 Gb WDC drivers connected as mirror. All drivers and updates are installed( sp3 and so on). A week ago PC changed its video mode to 256 colors (like VESA mode) and after several moments I got BSOD: c000021a: 0xc0000005 Doctor watson did not create dump although it is installed as default debugger.

• Windows 7: Setting up backup to an external hard drive on another computer on the network

  - by seansand

  I have an external hard drive connected to a Windows 7 (Home Edition) computer. I have another computer (with Windows 7 Ultimate), and I want to have the Windows 7 Ultimate back up to the same external hard drive, without having to disconnect and move the external hard drive from the Home Edition PC. When I get to the "Set up backup" dialog within Windows 7, it asks me where to save the backup. I select "Save on a network". However, when I enter "\\computername\harddrivename" under Browse, the "OK" button remains grayed out. The button remains grayed out unless I also enter a Username and Password under "Network credentials". However, the account I have on the other computer doesn't have a password for it. To un-gray out the button I must enter a fake password, allowing me to click "OK", but then obviously I get a "bad password" error. Does anyone know how to get around this problem? (Seems kind of ridiculous.) I made sure that the security settings with the external hard drive on the other computer are full access to Everyone, so permissions is not the problem. I also thought about using Homegroup instead of the regular security settings, but there is no obvious way to go about it that way, either.

• Skip Corrupt Revisions During SvnAdmin Load

  - by cisellis

  I have a dump file that I am generating from VSS with the use of the VSS2SVN script. I've tested the generated dump file before and some of the revisions are corrupt for one reason or another (binary data or long path strings seem to be the main culprit). This is fine. In the past I have used svndumpfilter to split the dump file, remove the corrupt revisions and continue to load the repository. It worked but took a lot of manual effort to start the load, hit the bad revision, split the dump file, continue loading the repo, etc. This dump file is pretty large (~5GB) and takes several hours to load. I think I know the answer to this but is there any way to simply tell svnadmin load to keep going and skip corrupt revisions? I know how to verify, backup, etc. the dump file and don't need any of that. I don't care about recovering corrupt revisions. I just want to start the load, walk away, and not worry about checking it every few hours to manually remove the corrupt revisions. Is that possible? Thanks.

• Cyrus: In practical terms, how do end users administer their shared mailboxes?

  - by Nick

  Let's say we have four customer service reps: Billy, Bob, Joe, and Tom. Tom is the department manager. There's a shared Customer Service mailbox on the Cyrus server that they all have access to. Tom, as the manager also has administrative privileges for the shared mailbox. They decide they want to create sub-folders a certain way, and Tom creates them. They're all running Thunderbird, so Tom right-clicks the main folder and chooses "New Subfolder". Now Tom has the Subfolders he needs and the other sales reps have... nothing! Because Cyrus created the Subfolders giving Tom "Full Access" permissions, and everyone else gets no access. So how does Tom give the other reps in his department access to the new folders? As far as Cyrus is concerned, Tom has permission to grant others access to his new mailboxes- But as far as I can tell, there's no option in Thunderbird for granting mailbox permissions. An IT staff member should not have to receive a support request every time someone wants to add a Subfolder to a shared mailbox. That's why we make certain users into mailbox admins in the first place! But asking (non-technical) users to SSH into an IMAP server to run cyradm seems like a bad idea too. Certainly someone has found a solution for this dilemma. Perhaps a Thunderbird extension for setting Cyrus permissions? Or something like umask that forces subfolders to have identical permissions to their parents on creation? And related, what about Sieve configuration? Is there anyway that can be done from the client machine too? Thanks, Nick
