- TITLE :Troubleshooting Directory Replicator Problems
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1
- ----------------------------------------------------------------------
-
- If you experience problems during directory replication, the following
- list of troubleshooting steps may be helpful.
-
- NOTE: Some steps only require that you note information for use in
- subsequent steps.
-
- 1. What operating system is running on the import computer? (Windows
- NT, Windows NT Advanced Server, OS/2, UNIX)
-
- 2. Is there anything interesting in the error log in the import
- computer? The applications log has entries for the replicator
- service and often contains useful information. Look at the logs on
- both the import and export computers.
-
- 3. What file systems are installed in the partitions pointed to by
- the import and export paths?
-
- 4. How many import computers exhibit this behavior?
-
- 5. What time zones are the import and export computers running in?
-
- 6. Make sure the import computer has Backup Operator permissions. If
- these permissions are not set up, errors 5, 1300, and 1307 will
- show up in the event log.
-
- 7. Are the import and export computers in the same domain? If so, are
- the password and user name the same in both domains? Do the
- domains trust each other?
-
- 8. Are alerts being received by administrative accounts? (Has the
- alerter service been started?)
-
- 9. Are there any extended attributes in the files or directories
- being replicated?
-
- 10. If the source directory is on an NTFS partition, are there any
- alternate data streams in the files or directories being
- replicated?
-
- 11. If the source or destination directories are on an NTFS partition,
- look at the access control lists (ACLs) on the import and export
- trees with File Manager. Does the Replicator local group have at
- least CHANGE privileges to these directories?
-
- 12. Is it possible that an account has a file open (on import or
- export) all the time? This would show up as a sharing violation in
- the event log (error 32).
-
- 13. Is there an REPL$ share on the export computer? (The share is
- created as a side effect of the Directory Replicating dialog box
- on the export computer. This dialog box also sets an ACL for the
- REPL$ share. Using the NET command or any other means to create
- the REPL$ share is likely to cause problems.)
-
- 14. If you run the NET START command on the export and import
- computers, do both computers show "Directory Replicator" (or
- equivalent) in the list?
-
- 15. If you are exporting or importing from an NTFS directory, does
- either tree have filenames that differ only in case? Which file
- gets replicated is not predictable. It is possible that the export
- computer will choose one file and the import computer will choose
- another. This results in the replication being out of sync.
-
- 16. If the export computer is running OS/2 or UNIX and the import
- computer is running Windows NT, is the export computer's local
- time within half of an hour of the import computer's time? If not,
- the Windows NT network redirector will "bias" the times. This can
- cause everything to be copied again and again. Replication may
- never occur.
-
- 17. Some versions of the OS/2 importer leave the archive bit set on
- all files imported, whether or not it was set on the export side.
- This too could result in continuous copying. One workaround is to
- set the archive bit on all files on the export computer. (Windows
- NT to Windows NT replication correctly clones the archive bit.)
-
- 18. Some LAN Manager 2.1a import computers do not set their status
- file to OK.RP$. The cause is currently unknown, but there are
- few side effects. Files will not be recopied each pass but a file
- comparison will occur. Except for the status file state, the files
- are correctly replicated. This behavior does not occur on LAN
- Manager 2.2 importers.
-
- 19. Some versions of LAN Manager for OS/2 and UNIX allow hard disk
- files with reserved names, such as LPT1 or COM1. This can cause
- problems and should be avoided. The Windows NT replicator
- currently lets these filenames exist.
-
- 20. There is a design limitation of OS/2 LAN Manager that you should
- be aware of if you are using it to replicate files. OS/2 LAN
- Manager only allows one set of credentials to be in use at a
- time. (The credentials consist of the user name and password.) If
- someone is interactively logged on to one user identification (ID)
- and the replicator is trying to use a different user ID, then the
- replicator runs into that limitation. Replication will be delayed
- until the interactive user logs off. On the other hand, if the
- interactive user and the replicator user have the same user ID,
- then replication is possible, depending on the value of the
- TryUser value in the LANMAN.INI file.
-
- 21. The OS/2 and UNIX LAN Manager importers are generally designed
- with a limit of 1000 files per directory. You should be aware that
- the "." and ".." directory entries use two of those 1000 entries.
- Also, some versions may have an off-by-one error that causes
- repeated file copies with exactly 1000 entries. This gives a
- practical limit of 997 files for those importers. The Windows NT
- importer does not have these limitations.
-
- 22. Are there some files being replicated from an HPFS partition
- (written by OS/2) to a Windows NT server? Do these files have
- extended attributes (EAs)? There may be problems with the EAs.
- OS/2 might have written the EAs in discontiguous parts of the
- disk; Windows NT does not support this. The directory replicator
- includes the EA sizes in its checksums, and they may be wrong in
- this case. The replication may stay out of sync permanently. You
- can use Windows NT to rewrite the same EA values to a single
- contiguous area, if you know the original EA values. Note that
- accessing an HPFS volume over the network while OS/2 is directly
- reading or writing the volume will work correctly.
